So ive been with my gf now for a few years and suddenly she tells me she has BPD( which i will not judge for, i deal with my own shit.... And after researching BPD  a lot of previous situations make sense now) . I love her completely. My problem is i dont know how to support her,  it feels like everything i say turns into a fight, or hurts her. Which in turn hurts me, makes me want to pull back because i dont know what to do. Its horrible. I want to learn more about BPD and how to understand it better, what i should and shouldn't do. 

She says she loves me, but then there are times where she has said she does not, or she just does not know what she feels, and looks at me with what feels like disgust.  How do i know which one of these feelings is the real one? I feel like im going to lose her, and i dont want that. She has an amazing beauty inside. It makes me feel insane..... And im sure its even harder  for her, and way more intense.

I DO NOT and WILL NOT give up on her, or us, but I just dont know how to approach this. I feel like we have been making progress when we talk about it, and it will take time to fully understand and cope with it,  and that i should not take it personally.... Its not about me, though admittedly its very hard to remember this( my own personal mental illnesses does not make this any easier). 

Tldr : Girlfriend told me she has BPD , I love her and want to be there for her. I need advice on how to proceed and not fuck up my relationship with her. 

Cheers
