roommate endangering safety
I've been having roommate issues. This morning I woke up, went out for breakfast, came home and there was a strange man in my roommate's bed. I've never met him before. My roommate was out with her mom. She had left a stranger in our own apartment with neither of us there. She says she has been out with him a few times. I feel that she is letting a stranger stay in our apartment without either of us there, which is endangering our safety. What should I do?
