You may try and contact her or try to talk to her again, I don't really know the full scale of it, But you may try and explain it to me better, What is the issue at hand?, And what other issues or problems do you have?, Sorry for the lateness of my reply to your current situation.

But I didnt kill myself bc of her, shes all I have left

Depends on how you feel honestly, if you care abt them and its really bothering you badly try and talk to them and go from there or if your just emotionally checked out talk to them abt it and move on

A situation like this is delicate and most things can be solved by talking but if they forgot abt you then it would definitely need to be addressed hope this helps

I’d suggest breaking up with her because she clearly doesn’t care too much about you bruh
