XH and I split 2015. He got remarried and so have I. We have 2dc. DS who is 17 lives with him since 4 years ago as we just didn't get on and he didn't like me moving on with my life. DD 13 lives with me and my new DH and stays at XHs every weekend.
DS1 is in army now and lives away most of the time.
In the past XH has had dd13 mon-wed over the school holidays and the weekends like normal. This year there is a week he says he can't cover cos he's going on holiday with his new family. I told him he needs to pay for dd13 to go to holiday club but he says she's too old and he won't pay to it .
She's been going to this holiday club each holiday for years and am fed up of this arguament because she says she's the oldest there.
My aibu is should that he should pay for her to be in holiday club and she's not too old she's 13 not adult.
