My adult son still lives at home (he and his sister who is at Uni are moving in with their dad in the summer) but I just want to check if IABU. He and his GF are both early twenties, and she does stay over sometimes, which I am fine with. I have made the house rules that it's no more than three nights a week, but she's starting working at a nightclub and coming back at 3.00 am and waking me and my dog up. I have asked them both to stop, in fact I got them both up really early the last time they did it and sent her home. She did it again this week and I talked to her about it and she apologised. Last night, 2.30 am out she gets from an Uber and they are banging about downstairs! I spoke to my son who apologised. I've just asked him to send her home now, and he said I am "not very understanding." I feel awkward and uncomfortable in my own bloody home. Historically whenever I have put a boundary down with these two I am called to a meeting by them a few days later where she claims I don't like her, so I've cut that off with him today and said I won't be doing that, it's her behaviour I don't like. My son't argument is that he shouldn't have a curfew as an adult which I agree with, but I made the point that she doesn't live here! AIBU? I would never have dared behave like his in my parent's home at any age!
