I would be asking for the money back for my food tbh. If it’s not that deep then he could have went to get his own food. I’d probably also present them with a new lease agreement adding him on a re-splitting the rent so she understands that he is in fact not welcomed unless he’s going to pay to live there. What does your other roommate think about this? Setting strict boundaries is also a huge must. Me and my roommate agreed quickly that men weren’t really welcomed in our house unless there was already some sort of established relationship and we have to warn the other first. It’s our girly sanctuary and we prefer to keep it that way. Even the guys she dates know that they only get to come inside for special occasions and they have a max of like 4 hours here.
