My parents and DH do not get along.
Up to now Christmas wasn't an issue due to a slight difference in cultures - my DP(arents) celebrate on Christmas Eve (24th of Dec) and DH family celebrate on Christmas Day (25th) like everyone else. So I would go to my DPs on Christmas Eve with DCs and we would all go to my PILs on Christmas Day.
However this year my DM started a new job and has told me there's a 99% chance she will have to work Christmas Eve so won't be able to celebrate on that day and will most likely be doing the meal on the 25th.
She heavily hinted she will want me there. And I expect a massive fallout if I'm not.
She knows we go to PILs on the 25th.
Due to the fallout my DH does not see or speak to my DPs at all and doesn't attend Christmas at their house. We have small DCs and I feel we should spend Christmas day with DH and his family like always.
I think if my DPs can't celebrate on the 24th they should do the 26th instead or at least not expect me to be there if they are adamant about 25th.
I know as soon as I bring it up it will all get turned on me and they will say how I'm putting PILs above my DPs or how "it's just one year" or how they expected me to make an exception etc etc
AIBU?
Is there any way to manage this without causing a fallout?
