My ex with HPD gave me a lot of mental errors in the past

non of them made sense and I can't stand stuff or situations that I don't get and not knowing why things are the way they are. In the beginning I still was crazy in love at her when I started my search for answers... Next phase I wanted to be "the one that fixes her" but learning more and more and looked at every personality disorder there is and comparing to see what PD matched best,... Talked about it with a friend who is a psychologist and agreed with HPD,... Now I understand most of her actions and feel sorry for her in some way, I know that I can't fix her or do something about it,... I think the only thing there is that's good is to be there for here and support her in life/recovery... Another great thing is that she realize that she has a mental problem, but deny it's HPD (I think she knows but is not admitting to me). Anyway I still love her a lot but not in a relationship kind of way... I truely care for her and just want her to be happy! Everything I do to make her see how great she is and try to beef up her self-esteem seems to fail... seriously Some good advice is welcome she don't believe my good intentions ether,...pffffff
