*BIG HUGS* I'm so sorry to hear this happened to you.

This was NOT YOUR FAULT. You are NOT a slut or sub-human or immoral or stupid. He took advantage of you.

I completely agree with archangelbeth's "cut direct" approach of ignoring him. Though even less something you're ignoring, but something you don't even see - like a smudge on the painted wall.
I also agree with the others who've suggested seeing a counselor. It would probably be very beneficial with helping you get your thoughts out and cope.
