I agree with you, Christine, that there are many variations of BPD and it would be difficult to generalize on intelligence or anything else. I think I read that there are over 400 different combinations of symptoms. I don't know why the media focuses on only one kind of BPD. Well, I do know. It sells newspapers! I am also "nice" and have stable relationships, never cut, and was never promiscuous. I'm a quiet borderline.
