Marriage and Borderline Personality Disorder

Many different kinds of close relationships are affected by borderline personality disorder (BPD), but perhaps none more than being married to a person with BPD. More specifically, marriages in which either one or both partners have BPD can be very tumultuous, conflict-laden, and dysfunctional.

Learn more about how your marriage may be affected by BPD, and how you and your partner (surprisingly) may not be destined for divorce as you likely might have thought.

Borderline Personality Marriage Statistics

Studies of marital status in people with BPD have found that about 60 percent are married (these studies were done in people with average ages around 40 years old). This suggests that people with BPD are less likely to be married than those in the general population—in the United States, about 85 percent of people are married by age 40.

Unexpectedly, people with BPD do not have higher divorce rates than the general population. By an average age of about 40, the divorce rate for people with BPD is around 35 percent, and this is comparable to the divorce rate for the average U.S. citizen. However, people with BPD are far less likely to remarry after a divorce. In fact, only about 10 percent of people with BPD get remarried by around age 40 which is nearly half the national rate of remarriage.

On an interesting note, research suggests that people with borderline personality disorder who develop a substantial reduction in their symptoms (defined as recovering from BPD) are more likely than non-recovered people with BPD to marry and become a parent and less likely to divorce or lose custody of a child.

Quality Matters

One way to judge whether being married to a person with BPD can be successful is by the divorce rate. Using this as a measure of “success,” it appears that marriages that consist of a partner with BPD are no more or less successful than the average marriage. However, this does not take into account the quality of the marriage or the satisfaction of the partners.

Unfortunately, there is limited hard research data on the quality of marriages in which one person has BPD. Of the research done, one study found a positive link between the severity of BPD symptoms and marital violence and distress. This means that the more severe a person's BPD symptoms are (for example, fear of abandonment or intense and frequent mood changes) the more likely there is violence, in addition to overall trouble in the marriage.

Another study found that BPD symptoms were linked to poor problem-solving and communication skills in a marriage. 

There is more scientific data on romantic relationships and BPD which offers some potential insight. Research has shown that BPD symptoms are associated with greater chronic stress, more frequent conflicts, and less partner satisfaction in romantic relationships.

Furthermore, some experts believe the quality depends a great deal on the personality of the non-BPD partner. Interestingly, there is research suggesting that people with BPD symptoms tend to marry partners who also report BPD symptoms—a phenomenon called assortative mating.

This phenomenon brings about a concern. It seems like it would be even more difficult to manage a relationship effectively and happily when not one, but both partners, have intense mood shifts, engage in impulsive behaviors, and possess an unhealthy sense of self—all symptoms of having BPD.

A Word From Verywell

The take-home message here is that even though divorce rates are not as high as one might except in marriages where one person has BPD, being in a relationship with someone with BPD can still be particularly stressful and challenging.

This is why in addition to the BPD partner getting treatment, it's a good idea to seek out marital or family therapy to keep the marriage, relationship and family functioning intact.
