I do care, and I was there for her.

I switched jobs to be in the same city as her, before meeting my gf, so i could support her. After meeting my gf is when she started becoming really passive aggressive. Drinking, drugs, etc. And lying about it. Whenever she'd be depressed I'd be there trying to help her but she would push me away. For a whole year it was like that. I couldn't take it anymore, she'd talk with other people as if she wasn't getting help and make herself a victim - but everybody: her friends, her family although far away and even myself tried to help her! She would stop communicating with us, she would give me and my family the silent treatment, she would leave the house and not be seen for days at times. What could I have done differently?? I tried the best I can for the time I was living with her. Any small thing felt like time bomb with her. She was seeing therapists but that didn't seem to have made any difference - she doesn't want help. She doesn't want to help herself. Even right now she's lying about having attempted suicide and is mad at everybody for calling the ambulance on her.

At one point she said she was diagnosed with BPD, months later she says she doesn't have it. She has some sort of personality disorder that I'm unsure about.
