Ex asked me to give up my allotted day with the kids this week (the only one that I am not working or that he does not have them) and I agreed but asked him to bring them back late afternoon so that I would have a reasonable time in the evening with them before they go to bed. He brought them over 2 hours late - no apology, no call to say that they would be late, no nothing. I know that he just did it so that he would have control over the situation as I am the main carer and he resents that. I am spitting. He is supposed to drop them at 5 on a Sunday when he has them over the weekend but that has been creeping to 6 so I have little time before bed. Should I Drop them 2 hours late when it is his turn next to have them and then explain that if he is not going to respect my time then I am not going to respect his? We wrangle over everything and are probably headed to court. I don't want to be unreasonable but feel pretty angry and revengeful. I also don't trust that he will bring the kids over at the right time next time and have people over for a barbecue that evening - including the DC's friends. I don't want to run things on his very unreliable schedule. Also - should I insist on my day back - so he has to give up one of his - or is it too late for that?
