Drunk hookup?

I went out drinking alone with my friend from school and I ended up getting ridiculously drunk. I kept blacking out but everytime I woke up he was on top of me and I was crying and then I'd pass out again. The more I think about it the more I remember, but I can't help but feel like it was my fault. I told a friend and he confronted him about it and now I'm scared he's going to be mad at me for saying something. I'm 18, he's 25. I have an uneasy feeling when I'm around him now. What do I do/how do I forget about this?
