Hi, dbtzk2000, and welcome to Psych Central! As seesaw said, we don't like to try to diagnose. After all, we aren't professionals, and even if we were, she would still need diagnosing in person.

I honestly don't think anything you do will make a difference with your girlfriend. You can try setting boundaries, but I think that would make her even more angry. Love cannot conquer all problems. She seems to have serious mental/emotional issues, regardless of any label she might be given.

I suggest you talk to a therapist about her. You will get some insights into her and into yourself. I agree with seesaw about wondering why you are happy to continue such a relationship.

Please keep us informed and again, welcome!
