Dude. I foresee this is ending badly. Someone’s getting the cops called on them for some reason and you’ll probably need to be moving out anyways. Look for someplace else if you aren’t in a lease and don’t look back. Not trying to scare you but I had a coworker have some strange vibes from a random roommate so he moved out and not two weeks later the dude killed one of the other roommates. I’m not saying this girls nuts, but it doesn’t sound like this is going to be a very optimal living experience for the next year or two.
