The Complex Interplay of Borderline Personality Disorder in Romantic Relationships


Borderline Personality Disorder (BPD) represents a significant challenge within mental health systems globally, affecting approximately 2.7% of the general population and presenting in up to 10% of psychiatric outpatients and 22% of psychiatric inpatients. Central to the clinical presentation of BPD are pervasive relationship dysfunctions, which have sparked considerable interest and investigation into their underlying mechanisms.

One prominent theoretical framework for understanding these relationship dysfunctions stems from attachment theory. This theory suggests that early adverse experiences, particularly those involving trauma and neglect from primary caregivers, lay the groundwork for the development of insecure attachment styles that persist into adulthood. Empirical evidence supporting this perspective comes from studies revealing elevated rates of childhood maltreatment and insecure attachment styles among individuals diagnosed with BPD. These findings imply a link between early relational experiences and the subsequent difficulties in forming and maintaining healthy relationships seen in individuals with BPD.

Expanding upon attachment theory, the third wave of cognitive-behavioral therapy, such as schema therapy, offers additional insights into the development of negative relationship schemas in individuals with BPD. According to this perspective, dysfunctional experiences in childhood contribute to the formation of maladaptive beliefs and patterns of interaction, which are then perpetuated in adult relationships. This suggests that early relational trauma may not only shape attachment styles but also influence broader relational schemas, contributing to ongoing interpersonal difficulties in individuals with BPD.

In parallel, biological models propose that chronic stress exposure during critical developmental periods may lead to dysregulation of the autonomic nervous system (ANS) and the hypothalamic–pituitary–adrenal (HPA) axis, impairing individuals’ ability to cope with relationship distress. While the precise mechanisms linking stress dysregulation to relationship dysfunction in BPD are not fully understood, research has begun to elucidate associations between stress response systems and interpersonal functioning in this population. This underscores the importance of considering both psychological and biological factors in understanding the complexities of relationship dysfunctions in BPD.

Despite significant advancements in understanding the psychological and biological underpinnings of relationship dysfunction in BPD, there remain notable gaps in the literature. Particularly, the majority of research has focused on individual characteristics of individuals with BPD, overlooking the dynamic interplay between partners within the relationship dyad. Studies indicate that partners of individuals with BPD often exhibit similar maladaptive traits, including insecure attachment styles and personality disorders, which contribute to heightened relationship discord. Notably, research has revealed elevated rates of domestic violence within BPD couples, with both partners being perpetrators and victims, underscoring the complex nature of relational dynamics in this population.

Moreover, while the psychological and interpersonal aspects of relationship dysfunction in BPD have been extensively studied, the hormonal underpinnings remain relatively unexplored. Notably, testosterone, a key hormone implicated in aggression, dominance, and submission, has been linked to relationship dysfunction and has been found to be elevated in individuals with BPD. However, the precise role of hormonal dysregulation in shaping relationship dynamics within BPD couples remains poorly understood.

In light of these considerations, a comprehensive study was proposed to examine relationship dysfunction in BPD couples from a multidimensional perspective. The study aimed to investigate attachment styles, childhood trauma history, hormonal profiles (specifically testosterone and cortisol levels), and interpersonal dynamics within BPD couples compared to control groups. Hypotheses were formulated based on existing literature, positing elevated levels of insecure attachment styles, childhood trauma, and neurotic personality traits in both partners of BPD couples. Additionally, it was hypothesized that BPD couples would exhibit higher testosterone levels and lower cortisol levels compared to control groups, alongside lower couple satisfaction and higher levels of relationship-related problems.

The exploration of Borderline Personality Features (BPF)

The exploration of Borderline Personality Features (BPF) in romantic relationships underscores the complex interplay between personality disorders, attachment styles, and interpersonal functioning. Studies emphasize that individuals with BPF often exhibit relationship dysfunction characterized by frequent conflicts, a hallmark feature significantly influenced by underlying factors such as childhood maltreatment, dysfunctional attachment styles, and neuroticism. These elements contribute to the instability and dissatisfaction commonly observed in the romantic relationships of those with BPF.

Research indicates that females with BPF display higher levels of childhood maltreatment and neuroticism, leading to more relationship-related problems and reduced satisfaction within their romantic engagements. Notably, male partners of women with BPF exhibit lower testosterone levels and share similar patterns of childhood maltreatment and dysfunctional attachment styles. This suggests that the intricate dynamics of BPF within romantic relationships extend beyond the individual, affecting both partners within the dyad. The study’s findings advocate for a holistic approach in treating BPF, considering not only the individual’s psychological aspects but also the hormonal and psychosocial parameters influencing relationship dynamics​​.

Further investigation into the romantic relationships of individuals with BPF reveals that insecure attachment and passive-aggressive communication significantly reduce relationship satisfaction. These patterns of interaction exacerbate the interpersonal dysfunction intrinsic to BPF, contributing to the disorder’s complexity and the challenge of fostering healthy romantic relationships. The development of a model for psychiatric nurses to facilitate the mental health of couples dealing with BPF underscores the necessity for targeted interventions that address the unique challenges posed by BPF within romantic relationships. Such interventions aim to promote constructive intra- and interpersonal relationships, highlighting the importance of understanding and mitigating the factors that contribute to relationship dysfunction in BPF​​.

The narrative review on romantic relationships of people with BPF further corroborates these findings, indicating that BPF pathology, prevalent among substance use disorder populations, is strongly linked to interpersonal difficulties, particularly in the context of romantic relationships. These relationships are often marked by instability, ineffective communication, and conflict. Addressing the fear of compassion from others, which explains the relationship between BPF symptoms and ineffective conflict resolution strategies, could offer a novel approach to improving romantic relationship dynamics among individuals with BPF. This approach underscores the potential benefits of interventions designed to reduce fears of compassion and increase comfort with compassion from both others and oneself, ultimately strengthening relationships and reducing the risk of relapse in substance use disorders​​.

Understanding Borderline Personality Disorder

BPD is characterized by intense emotional experiences, a distorted sense of self, and significant difficulties in maintaining stable relationships. Individuals with BPD may oscillate between extreme idealization and devaluation of their partners, driven by an underlying fear of abandonment and rejection. This fear can manifest in various maladaptive behaviors aimed at keeping their partner close, yet paradoxically, these actions often push their partners away.

Romantic Relationships and BPD

Romantic relationships involving individuals with BPD are frequently marked by volatility, with patterns of intense closeness followed by sharp withdrawals. This push-pull dynamic can be bewildering for both partners, creating a cycle of emotional turmoil and misunderstanding. Partners of individuals with BPD may find themselves on an emotional rollercoaster, characterized by periods of intense love and affection, interspersed with episodes of significant conflict and strife.

Challenges in BPD Relationships

One of the hallmarks of BPD in romantic relationships is the struggle with effective communication and boundary setting. Partners may perceive behaviors as manipulative when individuals with BPD attempt to meet their emotional needs in unproductive ways, such as threatening to end the relationship. This perception can lead to frustration and resentment, underscoring the importance of open communication and the establishment of clear boundaries within the relationship​​.

Moreover, individuals with BPD often experience intense fears of abandonment, which can lead to behaviors aimed at avoiding real or imagined separation from their partner. This fear can result in a cycle of behaviors that test the relationship’s boundaries, such as borrowing items without permission or probing into private matters inappropriately​​.

Strategies for Managing BPD Relationships

For those in a relationship with someone with BPD, understanding the disorder is crucial. Recognizing the symptoms and the underlying mechanisms can foster empathy and patience, essential for navigating the complexities of the relationship. Setting clear boundaries and communicating openly about needs and expectations can create a more stable environment for both partners​​​​.

Treatment options such as Dialectical Behavior Therapy (DBT) offer promising results for individuals with BPD, focusing on skills for managing emotions, improving interpersonal relationships, and reducing self-destructive behaviors. Supporting a partner’s treatment plan and engaging in couples therapy can also be beneficial strategies for improving relationship dynamics​​.

Borderline Personality Features (BPF)

Borderline Personality Features (BPF) encompass a range of symptoms that significantly impact an individual’s emotions, self-image, and behavior, particularly in how they relate to others. Understanding BPF, especially in the context of the latest research and treatment approaches, is crucial for both individuals affected by the disorder and healthcare professionals.

Core Features of BPF

BPF is characterized by a pervasive pattern of instability in interpersonal relationships, self-image, and affect, along with marked impulsivity starting by early adulthood. Individuals may experience intense episodes of anger, depression, and anxiety that can last from a few hours to days. Efforts to avoid real or perceived abandonment are common, which can result in rapid involvement in relationships that are intense but unstable. Impulsivity in areas that are potentially self-damaging, such as spending, sex, substance use, reckless driving, and binge eating, is also a hallmark of the disorder. Additionally, recurrent suicidal behavior, gestures, threats, or self-mutilating behavior, such as cutting or burning oneself, can occur​​​​.

Diagnosis and Treatment

Diagnosis of BPF typically involves a thorough evaluation by a licensed mental health professional who assesses symptoms, experiences, and family medical history. It’s usually diagnosed in late adolescence or early adulthood, but symptoms must be significant and last for at least a year if diagnosed in individuals younger than 18​​.

Treatment of BPF has advanced, with psychotherapy being the mainstay of treatment. Dialectical behavior therapy (DBT) and cognitive behavioral therapy (CBT) are among the most effective psychotherapeutic approaches. DBT focuses on mindfulness and emotional regulation, while CBT aims to change core beliefs and behaviors stemming from inaccurate perceptions and difficulties in interacting with others. Medications might be used to treat specific symptoms or co-occurring mental disorders but are not the primary treatment for BPF​​.

Recent Updates in a Postpandemic World

The understanding of BPF has evolved, especially considering the impact of the COVID-19 pandemic. BPF is now firmly established as a distinct diagnosis, separate from co-occurring mood, anxiety, trauma-related, and behavioral disorders. It’s also seen as a reflection of general personality dysfunction, with neuroimaging research highlighting a distinct neurobiological signature of interpersonal and emotional hypersensitivity. This understanding informs the psychotherapies and clinical management approaches proven effective for BPF. The treatment landscape has seen a shift towards briefer, less intensive therapy formats, with an emphasis on functional improvement and broader access to care through remote interventions​​.

BPF, a complex and multifaceted disorder, requires a nuanced approach to diagnosis and treatment. Advances in research and therapy have improved the outlook for individuals with BPF, highlighting the importance of early intervention, tailored psychotherapeutic strategies, and the potential of remote interventions to enhance access to care. As understanding of the disorder deepens, especially in the aftermath of the global pandemic, individuals with BPF have greater opportunities for recovery and improved quality of life.

Borderline Personality Features and Jealousy: A Comprehensive Analysis

The interplay between Borderline Personality Features (BPF) and jealousy within romantic relationships is intricate and multifaceted, characterized by a profound impact on interpersonal dynamics. This analysis draws upon recent insights to unravel the complexities of this relationship, emphasizing the pathological jealousy observed in individuals with BPF and its manifestations in romantic engagements.

Pathological Jealousy in BPF

Pathological jealousy, often marked by irrational preoccupation with a partner’s supposed infidelity without concrete evidence, emerges significantly in the context of BPF. This form of jealousy transcends the normal emotional spectrum, entering the realm of delusional thinking. Individuals with BPF, grappling with intense fears of abandonment and rejection, may exhibit jealousy that sometimes reaches delusional proportions during periods of intense devaluation or micropsychosis. The foundation of pathological jealousy in BPF lies in a deep-seated insecurity and an unstable sense of self, exacerbated by chaotic interpersonal relationships and self-defeating behaviors. The dynamic of jealousy in BPF is notably complex, as it intertwines with the individuals’ difficulty in forming trust, stemming from insecure attachment styles and a history often marked by trauma, neglect, or abandonment​​.

Comparative Perspectives on Jealousy in BPF and NPD

Jealousy within the frameworks of Borderline Personality Disorder (BPD) and Narcissistic Personality Disorder (NPD) presents distinct coping styles, neither of which fosters healthy interpersonal relationships. Both disorders involve a maladaptive processing of jealousy, driven by an unstable sense of self. Individuals with BPD tend to experience jealousy as a profound threat, often leading to punitive actions against perceived sources of envy. This contrasts with the competitive nature seen in NPD, where individuals may seek to outdo or diminish the achievements of others to maintain their inflated sense of self-worth. The challenge for both BPD and NPD individuals lies in moving beyond these destructive patterns to embrace more adaptive strategies for coping with jealousy, fostering intimacy and genuine connection in their relationships​​.

Implications for Relationship Dynamics and Treatment

The presence of pathological jealousy in romantic relationships involving individuals with BPF can precipitate a cycle of conflict and distress. This dynamic underscores the critical importance of psychotherapeutic interventions, specifically tailored to address the underlying issues of trust, self-worth, and emotional regulation that contribute to jealousy. Effective treatment approaches, such as Dialectical Behavior Therapy (DBT), can offer individuals with BPF the tools to manage their emotions, improve interpersonal skills, and ultimately, mitigate the deleterious effects of jealousy on their relationships. Engaging in therapy can also provide a platform for exploring the roots of jealousy, including past traumas and attachment issues, facilitating a deeper understanding and healing​​.

The nexus of BPF and jealousy presents significant challenges within romantic relationships, necessitating a nuanced understanding and targeted therapeutic strategies. By addressing the core issues underpinning pathological jealousy, individuals with BPF can achieve greater stability in their relationships, fostering healthier dynamics and reducing the propensity for jealousy-driven conflicts. The journey towards overcoming pathological jealousy in BPF is complex but essential for cultivating lasting and fulfilling relationships.

Borderline Personality Disorder (BPD) and its Behavioral Manifestations: An Analytical Overview

Borderline Personality Disorder (BPD) is a complex mental health disorder characterized by pervasive patterns of instability in interpersonal relationships, self-image, and affects, along with marked impulsivity. This disorder significantly impacts individuals’ lives, manifesting in various harmful behaviors, including self-harm and externally directed aggression. Drawing from recent studies and empirical literature, this article delves into the multifaceted nature of BPD, exploring its diagnostic criteria, prevalence of self-harm behaviors, and the implications of such behaviors on treatment and societal perceptions.

Self-Harm and Suicidal Behaviors in BPD

Self-harm, a critical aspect of BPD, encompasses behaviors aimed at causing harm to oneself without suicidal intent. Recent studies indicate a high prevalence of self-harm behaviors among individuals with BPD, with up to 80% of those diagnosed reporting instances of self-mutilation. A study published in the Nordic Journal of Psychiatry in 2023 revealed that compulsory admissions to psychiatric wards, often employed to manage self-harm behaviors in BPD patients, could paradoxically increase or have no effect on such behaviors. The study emphasizes that a significant number of healthcare professionals perceive these admissions as excessively long and potentially detrimental, advocating for shorter, voluntary admissions and enhanced outpatient care as more effective alternatives​​.

Implicit Cognitions and Self-Harm in BPD

Exploring the cognitive underpinnings of self-harm in BPD, a study published in the Journal of Behavior Therapy and Experimental Psychiatry in 2023, focused on implicit cognitions related to self-injurious and suicidal behavior. This research identified that individuals with BPD exhibit higher implicit self-identification with self-harm and death, compared to healthy controls. It underscores the complexity of self-harm behaviors in BPD, suggesting that while explicit attitudes towards self-harm might not be predictive, implicit measures reveal a stronger, albeit nuanced, association with self-harming behaviors​​.

The Role of Affective Instability and Treatment Efficacy

The relationship between affective instability, a hallmark feature of BPD, and self-harm behaviors has been subject to extensive research. A review in Current Opinion in Psychology highlights that affective instability plays a crucial role in the maintenance of non-suicidal self-injury (NSSI) and the elevated risk of suicidal behavior in individuals with BPD. It also discusses the effectiveness of treatment programs in reducing self-harming behaviors, indicating a pressing need for targeted interventions that address the emotional dysregulation central to BPD​​.

Towards a Comprehensive Understanding

The empirical evidence and recent studies reviewed underscore the complex interplay between internal and external factors contributing to self-harm and suicidal behaviors in individuals with BPD. The findings call for a nuanced understanding of the disorder, advocating for treatment approaches that are both empathetic and evidence-based. Enhanced outpatient care, shorter hospital stays, and interventions targeting emotional dysregulation could offer more effective pathways for managing BPD, reducing the incidence of self-harm, and improving the overall quality of life for those affected.

BPD is a multifaceted disorder that requires a multidisciplinary approach to treatment and care. By fostering a deeper understanding of its underlying mechanisms and adopting evidence-based interventions, it is possible to mitigate the impact of self-harm behaviors and support individuals in their journey towards recovery and well-being.

Intimate Partner Violence, Nonintimate Assault, and Criminality in the Context of BPD

Intimate Partner Violence (IPV) and BPD

Intimate Partner Violence (IPV) refers to behavior within an intimate relationship that causes physical, psychological, or sexual harm to those in the relationship. Studies have explored the relationship between Borderline Personality Disorder (BPD) and IPV, highlighting significant findings regarding both male and female perpetrators.

  • Male Perpetrators: Research indicates a strong correlation between BPD traits and IPV perpetration among men. Studies have found that men with BPD are more likely to engage in partner violence, with BPD scores correlating with the degree of abusiveness. The presence of BPD traits in male perpetrators has been associated with a higher incidence of violence, underscoring the importance of addressing underlying personality disorders in interventions aimed at reducing domestic violence.
  • Female Perpetrators: While research on female perpetrators of IPV in the context of BPD is less extensive, existing studies suggest that BPD symptoms also correlate with IPV perpetration among women. These findings challenge the stereotype that IPV is predominantly perpetrated by men, highlighting the need for gender-inclusive research and intervention strategies.

Familicide in the Context of BPD

Familicide, the act of killing one’s spouse, children, or other family members, is a rare but devastating form of violence that has been linked to BPD traits. Studies examining cases of familicide have found that perpetrators often exhibit features of BPD, including impulsivity and affective instability. This association underscores the critical need for early intervention and support for individuals with BPD, to prevent the escalation of violence to such extreme levels.

Nonintimate Assault and BPD

Nonintimate assault refers to violent acts committed by an individual against someone with whom they do not have an intimate relationship. Research indicates that individuals with BPD are more likely to be involved in nonintimate assaults, suggesting a broader pattern of aggression that extends beyond intimate relationships. This highlights the importance of addressing aggression in BPD as part of a comprehensive treatment plan.

Criminality and BPD

The link between BPD and criminal behavior has been the subject of considerable research. Individuals with BPD are more likely to engage in various forms of criminal behavior, including violent crimes. This association is thought to be related to the impulsivity, affective instability, and difficulty in managing anger that are characteristic of BPD. Addressing the criminogenic needs of individuals with BPD through targeted interventions could reduce the risk of criminal behavior.

Serial Murder and BPD

While serial murder is a rare phenomenon, studies have explored the psychological profiles of serial killers, with some findings suggesting a link to BPD traits. However, it is crucial to note that most individuals with BPD do not engage in such extreme forms of violence. The association between BPD and serial murder in the literature underscores the diversity of BPD manifestations and the need for nuanced understandings of the disorder.

In summary, the relationship between BPD and various forms of violence, including IPV, nonintimate assault, and criminal behavior, underscores the importance of comprehensive treatment approaches that address the underlying psychological issues associated with BPD. Effective management of BPD can contribute to reducing the risk of violence and improving outcomes for individuals with the disorder and their communities.

The Impact of Digital Media on Sexual Behavior: Sexting, Risky Sexual Behaviors, and Borderline Personality Disorder

In the contemporary digital era, the landscape of young people’s sexual behaviors has been significantly reshaped by the advent and proliferation of digital media. This transformation is most notably observed through the practice of sexting, a phenomenon that involves the creation and exchange of sexually explicit content via electronic means. The discourse surrounding sexting is multifaceted, encompassing a range of definitions that vary from broad interpretations to more specific delineations based on the nature of the content exchanged. This variance in definitions contributes to disparities in reported prevalence rates of sexting among youths, with figures ranging widely from 30% to 89% in some studies (Klettke et al., 2014; Scholes-Balog et al., 2016).

Research specific to regions such as the Republic of Croatia and Bosnia and Herzegovina reveals participation rates in sexting among young people to be between 33.7% and 64.4%, and 23.64% respectively, highlighting a significant engagement in these digital behaviors (Burić et al., 2018; Kričkić et al., 2017; Sesar & Dodaj, 2019). The exploration of sex differences in sexting behaviors yields inconsistent results, with some studies indicating a higher prevalence among young men, while others find no significant differences between genders (Jonsson et al., 2014; Morelli et al., 2016; Dir et al., 2013; Drouin & Landgraff, 2012).

The academic narrative on sexting bifurcates into two distinct perspectives: one framing it as a modern form of intimate communication among youths, and the other associating it with various risk factors and negative outcomes, such as blackmail and revenge (Hudson & Marshall, 2018; Ybarra & Mitchell, 2014; Levine, 2013; Choi et al., 2016; Walrave et al., 2018). This dichotomy extends to the broader discourse on risky sexual behaviors (RSB), which are influenced by a myriad of factors including condom use, the number of sexual partners, and substance use before intercourse (Ezzati et al., 2004). The negative repercussions of RSB, such as unwanted pregnancies, sexually transmitted infections (STIs), and sexual violence, underscore the critical nature of these behaviors (Štulhofer, 1999).

The discussion on RSB further encompasses the role of gender, with traditional views positing that young men are more prone to engage in RSB than young women, a stance that is gradually evolving with changing societal norms (Schmitt, 2005; Bancroft et al., 2004). Another dimension of this discourse is the association of RSB with borderline personality disorder (BPD), a condition characterized by emotional instability, impulsivity, and complex interpersonal dynamics (Sanislow et al., 2002; Sansone & Sansone, 2011). The intersection of sexting, RSB, and BPD illuminates a correlation where engagement in sexting is linked to increased sexual activity and a higher propensity for RSB, with BPD traits potentially exacerbating these behaviors (Klettke et al., 2014; Gordon-Messer et al., 2013; Dake et al., 2012; Brinkley et al., 2017).

This intricate web of relationships between sexting, RSB, and BPD in young adults from Croatia and Bosnia and Herzegovina underscores the multifaceted impact of digital media on sexual behavior. The findings of various studies reveal that sexting is not only a prevalent practice among young people but also a behavior intertwined with broader patterns of sexual risk and psychological profiles. As digital media continues to evolve, understanding these dynamics becomes increasingly crucial for developing interventions and support mechanisms that address the complex realities of young people’s sexual behaviors in the digital age.


Navigating a romantic relationship with someone who has BPD requires patience, understanding, and a willingness to engage in open communication and therapeutic interventions. While challenges are inherent, with the right strategies and support, individuals with BPD and their partners can build fulfilling, stable relationships. The importance of professional guidance and therapy cannot be overstated, providing the tools and support needed to manage the symptoms of BPD and improve relationship quality.
