My 15 year old son wants to stay over at his girlfriends house this weekend, sharing her room. They’ve been going out for 10 months and her mother is fine with this. I’m ok with him staying over but feel uneasy with the same room. I’ve already said that I’m not ok with them staying in his bedroom at our house until they are both 16 (because at least there are no legal issues then, even if I think it’s still too young to be having a sexual relationship). Any experiences of this? I’m going to speak to gf’s mum tomorrow but know that she’s a lot more liberal than us (fine with alcohol at 13 e.g.) . . . so just trying to get my thoughts in order and I’d appreciate anyone else’s experiences.
