My 13yr old dd has asked for a sleepover at her boyfriends house. She's a model student, doesn't wear make-up, is very sensible. She's been seeing him for about 3 months and he makes her very happy. In the past she's suffered anxiety and has had issues with confidence, she's finally making friends and has a close circle of sensible girlfriends. She says her relationship is not physical and they haven't even snogged. I just feel that she is too young to spend night at bf's house, even if they aren't physical but my arguing is thin. Please help
