<human>: Give me the gist of the text in a nutshell

So, me and my girlfriend have been dating for a year and a half. We are both in college, but we go to different schools that are about 4 hours apart. 

Its around the time in the school year when we plan housing for the next school year, so we have both been starting to work on that. The issue is that she wants to room with a guy that she hooked up with in freshman year (as well as two other guys in an apartment).

They're friends now and I completely trust her and know she wouldn't cheat on me. Its just that the idea of her living in a small apartment with a guy who has been with her makes me very uncomfortable. I am pretty sure that he would not try anything either, but at the very least he is attracted to her in some sense. The idea of him walking around in underwear, or her coming out of the shower in a towel (things that make home feel like home) really bothers me, all things considered.

She said she would find others to room with if I really felt that uncomfortable about it, but I also don't want to ask her to find others if I am indeed being unreasonable. I just want to ask people who aren't directly involved if they think I am being unreasonable if I ask this of her.

Thanks a lot guys!
