My mother has (or had, perhaps) BPD. From years and years of observing her numerous doomed romantic relationships, I think the old scientific factoid ‘‘the best predictor of future behavior is past behavior’’ is pretty apt. Every person with this disorder is going to manifest symptoms differently, however, considering that BPD is pretty much defined as ‘‘dysfunction in relationships,’’ this isn’t really something that can be glossed over.
I fully believe that people with BPD are capable of change – it seems to be a pretty consistent characteristic, in fact. But I would question the probability of a BPD being able to change within that relationship. This is because patterns of interaction are so very difficult to modify, even when both parties are heavily invested in the outcome.
My mother repeated the same mistakes with about, er, I’d say at least 15 different guys… she was married and divorced four times. She has a tendency to be attracted to loser men, and when I was growing up she frequently behaved like Chimera’s ex. I saw her mistreat, abuse and berate many, many, men, even driving some good, loyal ones to hate her and to bring out the worst in the assholes. And let’s get real, she sacrificed my well-being for some of those shitty relationships.
The end of her last marriage changed her in some way. She’s still kind of a serial dater, but her current relationship… well, the dude has some major issues, but he’s not abusive, and she’s lost her temper with him and for the first time in her life seems fully aware that it’s wrong of her to do so. I’ve never seen her behave more maturely in a relationship than she is behaving at this moment. She finally realized that her relationships fail because of her behavioral patterns, and is making an honest effort to change with this relationship. But she is also realistic that the relationship may not work out (another first) and really wants to change so that the future, wherever it leads, will be healthier.
My best advice for your friend is: don’t let the patterns get started in the first place. Set boundaries, stick to them, make it clear that you’re not willing to be the punching bag and place the responsibility where it belongs. If she becomes abusive, leave. There really needs to be a straight line between ‘‘abusive behavior’’ and ‘‘the door.’’ Not a threat – a reality. He needs to have the strength to be willing to walk away if things get out of control.
If the patterns are already established though, the probability that she will change is very small. The best he can do is try to change his own behavior and way of relating and see if that is sufficient to push her into behaving in a healthier way. If she doesn’t change, leave.
There is nothing in the world worth tolerating abuse.
