I should also mention this roommate has chronic pain. Some days are better than others. Last semester I let her get away with a lot of things because I felt guilty. This semester I've been a little more strict. I give her 2-3 days before I text her or tell her in person to do x thing.

I also know it wasn't 100% her fault. Her friend ended up asking to invite more people. And it just kinda snow balled. But, it does bother me she didn't ask them to quiet down or go to her room until the movie was over.

I'll definitely text ahead of time. Though, she did know my friend was in town ahead of time. I guess, I just assumed that since no one had seen the movie that no one would talk. It was just extremely frustrating.

I sent her a text! It went like this "Hey I was thinking about what happened as well. I know your friend invited more people and it kind of snow balled. It turned into a talking movie night. It happens to be a pet peeve of mine to talk during movies. I also didn't feel comfortable asking your guests to quiet down. My friend and I still got to have a movie night through. And it isn't that I don't like you. But, we have extremely different living habits which seem to conflict."

I really don't know how to address her thinking I don't like her. And maybe I do resent her a little bit.

I REALLY appreciate the reply!! THANK YOU!
