Borderline personality disorder (BPD) affects mood, personality and relationships

borderline personality disorderBorderline personality disorder (BPD) is a mood disorder that can put a strain on relationships. BPD is divided into three groups known as cluster A, cluster B and cluster C. Cluster A is when individuals are odd or eccentric and involves symptoms like paranoia or schizotypal personality. Cluster B are those who are highly dramatic, both emotionally and behaviorally. Mood disorders that fall into this cluster are antisocial, borderline or narcissistic. Lastly, cluster C are personalities that are anxious or fearful. These individuals are dependant, obsessive compulsive or antisocial.

The borderline personality disorder most likely to impair a relationship is cluster B because these individuals tend to be the most antisocial and can be quite unsupportive. Personality disorders are present in about 10 to 15 percent of the population, with cluster B affecting nearly nine percent, according to research.


Below we will go into more detail about personality disorders and relationships, and how you can cope and manage them.

What is borderline personality disorder?

Borderline personality disorder is a mental illness, which can result in mood swings, changes in behavior and psychotic episodes, all of which can greatly impact relationships. These individuals have difficulty regulating their emotions, so they may have low self-esteem, be impulsive and have trouble maintaining relationships. The National Alliance of Mental Illness estimated that 1.6 percent of the American population has BPD, but with so many undiagnosed cases it may be closer to 5.9 percent. Seventy-five percent of diagnosed BPD cases involve women, making it more common in women than men.

BPD and its effect on relationships

BPD and its effect on relationshipsWe now know that borderline personality disorder can lead to problems with relationships, but in what way? For starters, those with BPD often fear being alone and they latch onto others. Yet these unstable moods lead to anger and frustration outbursts, so their partners becomes hurt or upset by their actions.

Overall, because of the nature of BPD, these individuals are unstable in relationships, which in turn can harm the relationship. They may love intensely but can switch moods and emotions quite easily. They tend to have a “black and white” mentality and have difficulty seeing the areas of grey. They have a great fear of abandonment and do not want their partners to leave. Unfortunately, sometimes their actions lead to their partners leaving in frustration.

Those with BPD can be demanding and manipulative, so others may not be able to put up with that form of behavior and separate from the individual. People with BPD also have difficulty accepting change, so any change to the relationship may aggravate anger and mood swings.

Due to all the above factors, relationships can be quite difficult for individuals who have a borderline personality disorder.
