Dear Prudence,
My roommate met someone in an online game about a month ago, and they began to date instantly. For the past two weeks, he has been at our apartment constantly, even when she’s gone for work, often leaving him here alone with me for 10 hours at a time. I think his visits should be two to three days a week max and that he shouldn’t be in the apartment without her. She claims this isn’t a problem, as he “leaves me alone.” While it is true he mostly stays in her room, I just don’t like having a stranger in our apartment so often. My former roommate’s boyfriend sexually assaulted me, and having my current roommate’s boyfriend here so often is giving me anxiety; however, I’m not comfortable sharing this information when my roommate pesters me to explain why I’m uncomfortable. I don’t feel as though I should have to justify myself. Our lease says guests are allowed for two weeks at a time. I brought this up, and she made a comment about how he could leave for a few days and come back for two weeks. Am I wrong for thinking guests shouldn’t be left unattended when you’re sharing your living space? Is there a way to enforce her boyfriend not being here unless she is?
