I'm ashamed even while typing this.

Two months ago I discovered TRP, and acouple months before that I made friends with a girl who we will call "Crazy".

At that time she was dating a total scumbag, beat her and everything. He was a total cunt to her. Over the months she seemed quite stable but I also knew vaguely that she had a suicidal history but she made for good conversation so I continued being her friend.

Acouple months ago when I found TRP I just went through another girl leading me on. It was shitty I realized that Crazy was using me at this point for attention and compliments. When I realized this I tried getting out by just kinda getting out of her life but acouple days later she texted me saying she was going to kill herself and I ended up talking her out of it.

Fast Forward two months and she does this regularly, her new boyfriend just left her two days ago and she came to me crying about how she wasn't good enough and that she was going to kill herself (She drank bleach later that night) and freaked out at me just to come back apologizing the next day. I want out of this relationship desperately. I get nothing out of it anymore, I'm done with putting up with her BS and her using me as the "Dependable Male" but I cant fucking leave. She is suicidal and I'm worried if I leave her she will manage to actually do it this time. I just want out.

Please I need advice on this, I have no one else to ask without me seeming like selfish and "unmanly".

TLDR; I want out of a one sided relationship but she is suicidal and I worried if I leave she will kill herself.
