Does borderline personality disorder (BPD) affect relationships between family members, friends, or other people in the community? How could BPD specifically create troubles, and what can be done to resolve these problems?

Interpersonal Relationships

Many people with borderline personality disorder (BPD) experience intense and unstable relationships with others as a part of the disorder. Their relationships tend to fluctuate between being all good or all bad, and they can be unable to experience contradictory feelings when relating to the world or others. This black and white thinking, or splitting, can spill over into all relationships including those at school or work with peers, professors, and instructors, managers, and supervisors.

Idealization and Devaluation Cycles

If you have BPD, you may initially idealize a person or situation, throwing yourself into a relationship fully and without reservation. However, soon something may occur that conflicts with this idealized view, such as a harsh comment from a supervisor, a poor grade on a paper, or a fight with your partner.

This conflict can cause you to switch from an idealized view to one of devaluation. You may think that there is suddenly nothing good about the person or situation and there never was.

Heightened sensitivity to rejection (known as abandonment sensitivity) may trigger your devaluing reaction. This sensitivity can cause you to overreact to real or perceived rejections. The feeling of rejection is overpowering and consuming and can feel very real, regardless of whether it was truly meant or unintended.

In response to devaluation, you may erupt in anger, quit the related task, become aggressive, or just give up. It is possible that the person, relationship, or task will again be seen as ideal, but it is also possible that the negative view will remain constant or that the damage that occurred will be irreversible. Friendships can be destroyed, jobs quit, or classes dropped. It can be a debilitating experience with significant consequences. 

Treating BPD

Borderline personality disorder can have a significant impact on your relationships. Even with your family members, you may be sensitive to rejection, changes in plans, or feelings of being slighted. These distortions in thinking can make you feel isolated, lonely, and helpless. 

In the past few years, significant progress has been made in understanding and treating BPD, both from a psychotherapy standpoint and through the use of medications. There are many treatment options that have been proven to be effective. Specific therapies that have shown promise in helping with the relational aspects of BPD.

Dialectal Behavior Therapy (BDT)

Dialectal behavior therapy (DBT), sometimes called "talk therapy" is a form of cognitive behavioral therapy (CBT). It looks at cognition, or thought, and relates this to behavior, or actions. There are now other forms of therapy available that address relationship concerns with BPD, but DBT is one of the therapies that was first found most effective for the disorder.

There are four primary skills taught in DBT, with one being interpersonal effectiveness skills. These skills are designed to help people successfully state their needs in a relationship and manage conflict.

Mentalization Therapy (MBT)

Mentalization therapy (MBT) is a therapy that focuses on looking at your feelings, thoughts, and hopes, in order to see how they may be connected to your behaviors. MBT is a form of psychodynamic therapy that focuses on present situations rather than prior events and uses your relationship with the therapist to work through issues.

Using specific examples or settings, MBT helps you to analyze both your feelings and the feelings and thoughts of others in a specific situation. For example, if a friend of yours gets angry and leaves your home, you would address what feelings they had that may have prompted their behavior of leaving rather than focus on the behavior of leaving.

In some cases, inpatient treatment may be necessary for BPD.


While there are currently no medications approved to treat BPD, medication is sometimes prescribed by doctors to help manage BPD symptoms and improve your interpersonal relationships. Some studies have shown that certain medications approved for other mental disorders are effective in controlling symptoms like anger, impulsivity, depression, and feelings of isolation.

Results can vary greatly and it is unlikely that medication will completely eliminate these feelings, but you can most likely expect modest results. 

While medication may be a useful tool for managing your symptoms while undergoing therapy, many of the medications used have significant side effects. Before taking any new medication, talk to your doctor and your therapist about potential side effects and whether the advantages of the medication outweigh the drawbacks. For some people, the risk is not worth the modest improvements in symptoms. 

A Word From Verywell

Regardless if you take medication or not, when you have BPD, therapy is essential for improving your relationships with others and managing your other symptoms. Talk to your doctor about your specific needs and concerns to come up with a strategy to meet your unique needs.

Take the time to learn about some of the most common issues faced by people with BPD in their relationships. Dating and romantic relationships with BPD, in particular, tend to be chaotic and intense and it is important that both you and your partner understand some of these issues and how to address them before they become apparent.

If you are living with someone with borderline personality disorder, it can be helpful to learn some of the ways in which a diagnosis of BPD affects the whole family. While learning about BPD either in yourself or a loved one can leave you feeling depressed, learning to understand the common issues and seeking out therapy can make a tremendous difference. Family therapy, in particular, can make a huge difference not just for someone living with BPD, but for the whole family.
