Long story short H left me for OW nearly a year ago. He then messed me around for months going back and forth between me and her whenever he had an argument with her. Till I realised he was playing me and since then we have just been civil and focus on the DCs.
He has seen the DCs regularly and he does pay a lot of maintenance for them.
When we were originally planning for Christmas he was with OW and he said that he was going to spend most of Christmas day with her family and just see us in the morning. His parents invited me and the DCs to spend Christmas with them (like we would usually do before H left me) and I accepted.
We decided that he would have the DCs on Christmas eve till 5pm while I am in work. Then he would bring them home and see them again Christmas morning.
Then a couple of weeks ago he and OW had an argument and he decided he wasn't spending Christmas with her family anymore. He told me how he really wanted to see more of the DCs at christmas he had been a idiot etc so we revised the plan. He was going to have them Christmas eve while I work and then bring them home but then he was going to stay and help set up for Christmas get the DCs ready for bed etc. Then he was going to come back early Christmas morning and come to ILs with us and spend the whole day with the DCs.
I told him not to tell the DCs till he was absolutely sure that this was his plan. He was insistent that this was his plan and he was focused on the DCs.
As the DCs have been asking about Christmas and he has been telling them how we will all spend the day together and all the fun things he will take them to do on Christmas eve while I'm working and the DCs are really excited about it all.
This morning he came to pick them up and told me he needs to chat. He and OW are back together his original Christmas plan was back on and he couldn't have the DCs for most of Christmas eve anymore and instead he will come to visit them around 6ish on the 24th instead. He also said that we could tell the DCs about the change of plan together when he brings them home later.
I said no, A. I'm working Christmas eve so if he is changing plans then he needs to find childcare. B. He has promised the DCs all these amazing Christmas eve plans. C. He is going to visit them right before bedtime wind them up and then leave them upset for me to deal with on Christmas eve when I will have loads of other things to sort. D. His parents have already bought food etc for Christmas day. I lost it and told him he is messing everyone around and causing everyone upset and he doesn't care. I told he that he can tell the DCs by himself because I'm fed up of having to pick up the pieces. He saw his arse said I was jealous and stormed out with the DCs.
He has since text me saying that his parents can't watch the DCs on Christmas eve and I will need to ask my dad. I messaged back saying No his mess he can sort it either he finds someone to watch them or he has to have them on Christmas eve he can contact my dad himself and ask if he wants but I'm not sorting it for him. He text back saying I was being deliberate awkward and he is just trying to make everyone happy. He also said that is the DCs who are losing out if I don't help him work something out. I haven't replied yet because quite frankly I am pissed off and I will probably say something I regret.
He is right I am being a bit awkward I could just message my dad or my brother or a mate to look after the DCs but I am so annoyed that he is expecting everyone to sort out his mess.
So AIBU to not sort out his Christmas eve mess. On the one hand its his mess that he has caused but on the other hand it's the DCs who should come first so I should really just suck it up for thier sake.
