My ex turned up last weekend and casually announced that he is going on holiday with his gf for 10 days in October. Therefore just assuming that I will be able to look after the kids.
I am fuming as he expects me to take my holiday to have the kids at the weekend (when my partner also works). For info he has the kids every sun and 3/4 Sat's so I can work, the weekend I don't work Saturday I have them. He doesn't see them in the week.
Aibu here? Honestly I don't get what makes him think it's OK to do this without running it past me first. I can't guarantee holiday for that weekend will be approved, and it's so rude to think he can just leave it with me.
To add, if he had come to me with some dates and asked when I would be able to have the kids so they could go away I wouldn't have had an issue.
