My ex husband is planning to take both children away for three days in two weeks time - he's already booked the flights. I've said I don't want them to go - they have been before and came back exhausted (the youngest one slept for the whole day after returning ) also my ex husband was quite drunk during the holiday and his friends looked after them quite a bit. I have also said that I don't think the school will approve the absence but if they do I don't see how I can object. I understand that he is notifying the school on Monday next week of his plans in the hope they do not respond in time and he can take them on holiday and make out he didn't realise the process for requesting leave. Also, he is going to ask his brother to pick the children up and take them to the airport as my ex husband will already be abroad (they will be joining him) but his brother doesn't know any of this background. Both children are being really difficult with me as they want to go saying I'm overreacting, they deserve a break as they have worked so hard, I'm no fun etc. Also, both children have school trips next week and my ex husband has told them not to return the passports to me. If they go the repercussions will be with the school, the children thinking they can do what they like, my ex husband undermine me. If they don't go my ex husband will 'forget' to pay maintenance and the children will be difficult with me. He's done this before. When we divorced he wanted shared parental responsibility and I didn't go to court to make contact arrangements with the children as he wanted to be free to see them when he wanted, he also didn't sign any divorce papers I had to wait years and 'serve' papers on him but we have been apart for 10 years, the children are 11 and 15 and it's getting worse. AIBU? WWYD?
