I'll try and make this as simple as possible, it's not. I've got three primary school age children. Two are in beavers and one is in scouts. DH is a leader at DD's scout pack and the DS's 1&2s beaver pack is run by a leader and a couple of students from the local university, one of whom is female. My husband is good friends with this girl and all three DCs adore her, they seem to have this older sister/cool aunt type relationship with her. They love telling her all about their day, new toys etc.
Recently the girl has started helping out at scouts as well, over the past six months this girl has been spending more and more time over at our house. It used to be the odd meal after scouts, but now it's every night till after midnight, if we have been drinking, she stays the night. She comes on almost all family days out, quite often with out with out me (which I don't mind as I'm fairly sure she is a lesbian and it enables me to get some work/house work done).
Now DH has invited her on holiday with us this summer, the kids are ecstatic about this, AIBU unreasonable to be pissed off? I feed this girl at least 9 meals a week and she never seems to pay on these days out. She's nice enough but I never seem to get alone time with my DH and DC. I don't think she has designs on DH but I'm worried that if I put my foot down and ask her to spend less time over hear that DH won't support me and the DC will hate me. What do I do?
