Hi BlueberryDonut.

I am so sorry this poor excuse for a human being put you through this. It is 100% not your fault. I can understand feeling guilt about being assaulted, being abused, etc.

I think it comes with the territory of such things.
I think being in college is a very hard time socially, and I just want to reiterate that you didn't do anything wrong. You froze, which is a completely natural reaction to sexual assault. That guy sounds like a he has problems. Big ones.
I'm glad you have a good boyfriend, who is understanding and kind. You deserve it! I'm glad you are getting counseling too, in order to cope with this. I hope it helps!!
