Not for sure but I was engaged to someone with disorder. I did not understand why someone who was so wonderful would feel so horribly about herself...until I met and got to know her mother who is a terrible awful monster. Guess she convinced my former fiance pretty good because I could not for the life of me convince her otherwise. I empathized with her until she started treating me the way her mother treated her. You though, admit this diagnosis and are open to getting help...she did not. We both worked for some pdocs at the time and if they had not told me, I would still wonder why things ended up the way they did. There was a lot more to it in my situation though. PM me anytime
