Borderline personality disorder. An ex had it. Even when it's not malignant and there's treatment and awareness of disease, it is very challenging. It makes it very hard for the person to live congenially with anyone. It sucks to see an otherwise nice, fun and lovely person get self-sabotaged so badly that they can't keep any relationship for long. Cognitive behavioral therapy helps, a lot, though.
