So after my roommate unceremoniously allowed a random person to stay in our flat (during my pregnancy), I had a talk with him and thought the situation was resolved. I wanted to throw him out but decided against it for financial reasons. Now another situation is brewing and I honestly can't tell if I'm overreacting -- some of my friends say I am, some say I'm not. This roommate is suddenly having a lot of random friends visit. The other day, he had a male friend stay over and was courteous enough to warn me in advance. It wasn't a problem, they weren't loud and the friend left early the next morning. But now, this morning, my roommate crept out of the flat very early, at about 6 a.m. I noticed that he shut my door before leaving, which struck me as strange, cause he never does that. So I got suspicious and figured "Uh oh, maybe he's trying to sneakily bring someone back?" I was right. He soon came back with some other random person and they went into his room. Again, it's not as if they are being loud or anything, in fact they're quiet as can be, but I'm weirded out by the fact that he shut my door in an apparent bid to keep me from noticing. And I worry because he is all into couch surfing. For those of you who don't know who that is, it's when you meet travelers and backpackers online and either let them stay at your place or ask to stay at theirs. I know the girl who stayed here was not a "couch surfer," but I'm beginning to wonder if these other people are. And if they are, that's really scary, that I am about to give birth and there are complete randomers in my flat. The problem is, it's not as if he is forbidden from having guests over. I can't throw him out for another month, and apparently the little talk I had with him didn't help things at all, it just made him start trying to conceal things. Is there anything I can do short of throwing him out? This makes me so uncomfortable.
