I'm just reading up on this thread and I'm really sorry about what happened.
If you reported, it'd be something to do for
you. If all you want is not to have to see him in your building, I don't see why you shouldn't be allowed to raise that with whoever manages your dorm or supports students at your school. If making a police report (which wouldn't necessarily leed to jail) is another step you want to take the outcomes wouldn't be your responsibility.
I don't think it ruins someone's life to be held responsible for their actions, if anything it gives them a chance to come clean and address their behavior... whether or not he did that would be up to him.
On relationship stuff, it sounds like you're doing a really good job of weighing up the different factors, and you have done an awesome job of stating clear boundaries and doing communication, which he ignored. So in terms of how to have a relationship? I think you're actually pretty good at that, and that he
is the only person here who clearly does not have much of a clue.
What you said describes classic abuser behaviour. This is far more often what assault and rape look like compared to the 'dark alley' situation. Most abuse and assault comes from people we already know rather than strangers (although that does happen too).
I also want to pick up on something from your first post. The hymen isn't something that is broken or unbroken... it's not even strictly speaking a 'thing' at all. There can be folds in the walls of the vagina that wear away over time, but they don't have nerves to cause pain and they don't 'split' or 'break'. I just wanted to mention that because if you felt that idea was leading you to feel dis-empowered here then it's worth knowing!

Having a sex life doesn't need to be painful, and having relationships doesn't need to be abusive. All of it can be pleasurable and enjoyable. Again, this is on him. And however you want to go forward with reporting, we totally support.
