Have NC for this as giving details he and the OW would recognise.
Have been apart from DC father for 4 years now and in that time they have stayed with me for Christmas eve and Christmas day, usually going to ex-H for Boxing day for a day or 2. They are currently 8 and 6.
Ex-H has them one weekend a month, Fri eve to Sun eve. He also has them for 2 hours each week for tea one night. That's it. He has never had them for any of their school holidays, he has never dropped them to or collected them from school. He plays no part in their day to day lives, does none of the 'work' involved in parenting. This is all his choice, he never asks for additional time with them. The day or 2 he usually has them at Christmas has in the past been instead of his usual monthly weekend.
He has asked me if he can have them for Christmas Eve and Day this year. I haven't yet replied and am in two minds. Although we have zero goodwill or relationship, I do try not to antagonise the situation further. Due to the minimal time he sees the children we have very little contact which suits me perfectly.
What I really think is that he can get lost, I do all the work, all year round so I should get the most exciting day of the year with them. He does nothing so why should he? If we had a proper shared parenting relationship then fair enough, take it in turns but we don't.
I could ask them what they want to do, I am pretty sure they would say they want to stay at home but I don't want to put them in a position where they need to choose.
What says MN? AIBU in saying no?
