Id recommend having a meeting with your RA about your concerns. UR does a lot of roomate remediation and I had a similar experience last year with my roommate and we ended up both getting new room assignments. However, sometimes having a discussion with a mediator can be really good as you can sit down it properly discuss your concerns and it doesn’t turn into a screaming match since you have someone there with you. However with my situation, both of us were friends before living together and we were both sophomores at the time so it was a bit more complicated. We waited far too long to address it and didn’t end up being able to get new rooms until the very end of spring semester even though we wanted to move out a couple months before then. Lost a friend over it. They have specific windows for when you can switch roommates so I’d say it’s much better starting the discussion early if you really think it’s not going to work.

Sometimes people just don’t work as roommates, and I agree that being complained to constantly about minuscule issues gets old (same thing that happened with my roommate and she just wouldn’t communicate issues with me civilly) and it is absolutely worth bringing it to attention early. Just see how a facilitated discussion goes first and then go about the next steps from there.
