Around 3 am, a friend told me someone had been in the upstairs bathroom for the past hour. It was her and her boyfriend. She passed out in my bathroom and I'm fairly certain they were doing stuff. Her boyfriend put her on my bed (after she had been rolling around on the ground outside. Thanks) and she slept there until about 4 am. I would have let her stay but I really didn't want her boyfriend to stay over because he's super SKETCH (probably the sketchiest guy I've ever met) and I know she and him would have had sex on my bed.
She mumbled to me in her drunken state, "Can't I stay here?" and I said, "No, you can't." I still feel guilty but I'm wondering if I should have just let her stay.
