Dear Prudence,
I live in a very nice, spacious apartment with three really good friends and my partner. Recently, one of my roommates has gotten into a whirlwind romance with a woman from his work. They have been dating for four months and now want her to move into our apartment. We have the space, and the extra money would be great, but I’m concerned. His girlfriend can be very difficult and sometimes loud (we’ve recently gotten a noise complaint because of her), and she makes rude comments that make me feel bad about myself. I don’t want to be the bad guy who stops her from moving in, but I don’t want the next year to be complete hell. The apartment was split down the middle as far as letting her move in, but now it seems like everyone but me and my partner are on board. Should I just let it happen?
