Ok now that the context is sorted out…she’s way too comfortable invading your space. Spending 15 hours a day in your boyfriend’s dorm??? That’s insane, and that’s not mentioning the invasion of privacy going on with her staying in the bedroom when it’s clear you’re trying to spend time with your girlfriend in there. At minimum, I’d set the boundary that if you’re with your gf in the room you expect some space just like you try to give them/her.
Ok I just saw this. It doesn’t matter if she doesn’t like being wrong it’s not her dorm room. I wouldn’t be surprised if the reason she spends 15+ hours in her boyfriend’s dorm is because her roommate doesn’t let her overstep boundaries like this. If she won’t listen and your roommate won’t handle it, then it’s time to get the RA involved and cut down how much time she spends there.
