<human>: About 5 months ago I found out that my best friend, that's a girl, I had a crush on since high school, liked me. We started talking but she was kind of iffy about the whole thing, and wasn't sure if it was the right time to start dating for her(she just got out of a long relationship in which she ended up very hurt.)

At the time I was going through some personal shit which was effecting everything from my job to my family and friends, and I just couldn't deal with getting hurt so I gave up even though I still liked her.

Fast forward two months and my best friend (guy) asks me if it was ok for him to start talking to the girl. And for some reason I said yes even though everything inside of me was telling me to just say no because I still liked her a lot. Fast forward a month and they're dating.

I hang out with him almost everyday, and I talk to her all the time too. But its fucking killing me. He always talks about her and shit, and I cant help but feel like hes not a good boyfriend at all. Actually, I know hes not. He has cheated on her already and pretty much just uses people. Hes pretty much a sociopath. I love him to death but hes a fucking asshole.

I just dont know what to do and I guess that's why I'm here. I really like her and I dont want to see her get hurt like I know she will. And I think she still likes me but I dont know really. Any advice would help please. Thanks.
