Let me make one thing perfectly clear.
He absolutely was NOT just told what was happening.
We have been together for 20 years. This is our 21st Christmas together. This way of doing things, my family one year, his the next, has ALWAYS been the plan.
Not only does it work for us, but his siblings are with their in-laws the same year In with my family, and my siblings (I have four) go to their own in-laws the same year we are with MIL.
Its a well oiled plan that has worked for 2 decades and involves over 20 people, who all find the arrangement very convenient and fair.
The only time this plan has ever been deviated from is 2023 when she lost her husband and we all cancelled everything to be with her on Christmas day and still kept to the arrangement of seeing her on "her" year last year. Which was the very least we could do. My mum was on her own on this year and decided to volunteer at the local homeless shelter.
I haven't been with my own family at Christmas since 2022 and I lost my own father just 15 months ago, as I said.
MIL is not being excluded. I don't know for sure what my siblings-in-laws plans are, but MIL is absolutely welcome at our house if she wants to come.
Failing that, she gets an entire Christmas with all of her family on boxing day. Not just a pop-in-and-see-you thing but an entire Christmas day with presents, family dinner, games, the lot.
She is not neglected
The more I think about it, the more I wonder why I posted this. Of course it's OK for me to want my husband with me and our Children on Christmas day.
