So back story DH and his ex used to share his kids over Christmas so one had Xmas eve until lunch and then the other got from lunchtime until Boxing Day. His ex wanted to swap this arrangement for a few years to fit around her husbands children and DH always refused as wanted to see his kids at some point on the day.
Last year ex told him he could have them all the way through to Boxing Day it was easier- I told him that would mean she would have them this year all through as it would fit in with her husbands kids so he needed to accept that if he had them last year. low and behold she is having them all Christmas this year!
Now my point he has refused to get anything for Christmas, has made no effort and is miserable and grumpy. I am sick of it and told him next year when he has his kids he can do and sort everything as he clearly only ‘helps’ when it’s for his kids - he has sulked off to bed.
AIBU that he only contributes and helps when his children are here
