DD is 14 and y9 She's not 15 until December. She's been dating a boy who's just turned 15 (he's y10 though) for a few months. He's a nice boy and he's been here for tea a couple of times.
Yesterday, DD asked me if she can go to one of his friend's houses next weekend (these friends are 15 and I think one of them is 16). I don't know who these friends are and I think there'd be about 4/5 of them. I've said no, which DD is unhappy about and thinks I'm BU and she said she knows these friends so it ‘doesn't matter’.
AIBU? Just looking for an outsiders opinion.
