I'm still not convinced it was rape, but I have no doubt that my psyche reacted as though it was.
I can't help but feel like there was SOMETHING I could have done differently.
I mean, at the time I felt like I didn't have a choice, but now I can't drop the feeling that I really did.
I understand this. And I'd like you to know that what I'm about to say is meant in the spirit of support, not criticism.
You are right - you could have done things differently. But also, at the time, you didn't understand/believe that you could. Both of those things are true. And I would actually agree with you - I don't think it was all rape. But I also fully understand you knowing that your psyche had such a strong negative reaction, especially when you were in pain and did not have the ability to make it stop. So in that sense, yes, you experienced rape.
It's complicated stuff. I'll offer this, if it helps. My trauma began with me getting into a car willingly, even wantingly, but it was a terrible choice and I truly should have known better. I knew even then that I was doing something I was not supposed to do. But I liked the guy, and thought he liked me, and that just won out over all my judgement.
I will regret that choice forever. And it's something I struggle with, still - accepting that I did have a choice, and I made the wrong one.
But: he had motivations that were not the same as mine. What he wanted was not what I wanted to give. And in that regard, I am not to blame. I did not want what happened. He is responsible for his choice to take advantage of my youth, my naivete, and my pliability. He chose to hurt me, I didn't choose to be hurt.
So yes, you were dating this guy, and he said, lets go have sex, and you went with him into the bedroom. That was something you now know was a choice. Back then, you didn't perceive the choice. He made his own choice to use you sexually, and he chose to take what he wanted despite what I can assume was your obvious distress and discomfort, and unreadiness. You aren't responsible for his choice, there.
What you did, going into that room, was a mistake. What he did, by continuing to use you sexually despite your pain and wanting it to stop, was more than a mistake, it was morally wrong, and probably criminally wrong as well.
Can you see how a mistake and a moral wrong are not the same as each other? It's hard to come to terms with big mistakes, it really is. That's part of what you need to work on. But another thing that can maybe help, is letting yourself understand that he did a wrong thing. Not a mistake. And you were the victim in that situation.
