I don't know how to tell my boyfriend i was raped
I've been dating my boyfriend about a year and a half now. Back when we had only together for a year, we went to a party that a common friend was hosting. We both ended up getting kind of drunk, and so our designated driver was a friend of his that was going to take us home. My boyfriends house was closer, so he dropped him off first. After that he drove out of town, pulled me out of the car, and did things to me I don't want to say. I think he knocked me out because I remember waking up at home.
Its been six months, and I get terrified every time I see him around campus. I don't know what to do because I have no proof he did it.I'm always having to make up some excuse for why I don't want to be around him. I don't know what he might do if he found out I told someone, so I haven't. But last week my boyfriend tried to make an advance farther than he usually does, and I panicked. He's realized something's wrong, and I don't know how to tell him. What should I do?
