Did you ask to be in a limited visitation/no overnight visitors dorm and got stuck where you are now?

If you don't ever want any male overnight guests in your room - for your roommate OR you - then talk to the housing poobah and see if you can switch to a limited visitation dorm next semester. There's probably someone in the limited vis dorm who's miserable and would take your place in a minute.

It sounds like she's being inconsiderate, but if you are in a dorm where overnight guests ARE allowed, for you to tell your roommate you are refusing to follow dorm policy is inconsiderate as well.

If you go to one of those hippie colleges where everything is 24 hour visitation, again, talk to the housing poobah and see if you can be matched with a more like-minded roommate.
