ok, so OH gets up this morning and decides to spend the rest of the holidays with his mother. We have 4 children, I could count on my hands the amount of times his mother has visited them, the eldest is 8 years old. She hasn't given them anything for Xmas and didn't even phone on Xmas day to wish them a happy Xmas, she lives a 2.5th drive away and I don't have a car, whenever they have family dinners/parties etc OH is invited but me or our kids are not, AIBU to expect that he spend his one week off work here with his children and if he wants to see his mother then she could have come up to see him?
