DC (8&6) alternate Christmases with DH and I and my EXH and his family. EXH has them EOW. DH and I do absolutely everything for DC in financial and practical senses. EXH doesn’t pay maintenance (lies to CMS), I do absolutely everything school related, we buy all of their clothes, DH takes them to and from their clubs. EXH doesn’t even have clothes for them when they go to his, I have to send a bag of stuff. Obviously I’m not looking for praise on this, I’m just stressing that he does nothing practical for them. He picks them up EOW on a Friday evening, from mine, not school (he never would be there on time, usually picks them up 6-6:30 pm) and brings them back on a Sunday either at 4pm or 8pm, whichever suits him best and never the agreed 6pm, feeds them rubbish all weekend, let’s them stay up late and get out of their routine (which is a pain on Sunday evening/Monday morning as they’re exhausted). They’re due to go to his this Christmas but to be honest, I’m fed up of giving him half of the Christmas’ when DH& I do all of the parenting and everything for DC’s. If he was a proper co-parent then I really wouldn’t mind but he literally isn’t, even on the days he has them I have to wait and work my schedule around his pick-up/drop off time which is always much later or earlier than it’s supposed be. He lives with his parents and DD has recently told me that sometimes they’re watching the DC for most of the morning/early afternoon as he doesn’t get up but they’re up. Yes, I know I’m ranting a bit but AIBU to not alternate Christmas with him anymore based off what I’ve said?
