Hi just checking if I’ve made a mistake. DD17 has been with her boyfriend almost 2 years. They live an hour apart met through a shared activity in between where they live. When they’d been together about 6 months we started to allow separate bedroom sleepovers at weekends to save parents driving late on a Saturday night. All fine they stuck to the rules. Now they are older my DD asked about sharing a room, I agreed but with some boundaries. I didn’t mention it to boyfriends mum, we communicate via text and occasionally see in passing but he is now almost 18 and drives so see her less. He’s told her about sharing a room and she’s messaged me, I think annoyed I didn’t ask her, to be honest I didn’t think as he’s almost an adult but in hindsight maybe I should have? I’m not sure how to reply.
