I'm so sorry this happened to you. Something very similar happened to me (wouldn't leave me alone/stop touching me, too drunk to make it home myself, etc) and I want to echo - this is no one's fault except HIS. He is the one who took you to his place when you assumed you were going to someone else's place, he is the one who didn't care that you were crying, he is the one who didn't take you home as soon as you asked to go home, he is the one who saw you so drunk that you were throwing up and didn't go, "Hmmm...pretty sure this 'consent' is forced/sex is not what she wants/wow, she can't even legally consent at this point." He was manipulative, he is a horrible person, and he is the one who should be ashamed of his actions.

For me, I had to come to realize that my "giving in" was instinctive and an attempt at protecting myself/getting myself out of a bad situation and I can't really be mad at myself or make myself feel bad for trying to keep myself as safe as possible, given the situation I was in.

Therapy was helpful for dealing with the feelings of guilt and shame that came after. Most colleges have a free counseling center...and while they often say there's a limit (for instance, at my college it's 5 per semester), the counselors can waive that limit for more serious matters.

Take care of yourself. That is going to be even more important than normal right now.
