Dd turned 17 yesterday and while 16 she met a boy working together in a restaurant. He turns 19 in march. There relationship has progressed beyond friendship but she says they are seeing each other but aren't boyfriend and girlfriend. I get that and that there's a period before kids go official. Dd wanted to stay over at his house tonight.... she asked at midnight. She isn't on the pill and I said I want her to be protected before sleeping over. DD said she doesn't want to stay to have sex. I said there is a risk things might happen in the heat of the moment and I'd rather she planned for that before sleeping over. My wife thinks the age gap is too big because they are in different places in life but I say that's not up to us, ultimately. My wife says she would accept it if they were official bf and gf but I understand there's a transitional period. We obviously want to make sure she focuses on her studies (she's head girl, a smart kid). Sorry about the stream of consciousness as I'm not really sure what I'm asking but if anyone can unpick and advise I would be most grateful.
