Am I being unreasonable?

My partner is trying to force me to spend Christmas Day with his family, I don’t celebrate Christmas as I’ve always disliked any ‘family celebrations’ from a kid. I made it clear to him from the very first time we spoke about Christmas plans that I will not be participating plus we’ve been together 6 years I would’ve thought he’d know by now. It’s been bought up tonight when I asked what they plan to do tomorrow and now I’m all the names under the sun and I will just be ruining Christmas for everyone else🙄 the past 3 Christmases I have taken the children to grandparents to celebrate Christmas, this will be the first year they’ve spent with their dad and his family, I was looking forward to just having some alone time and being on my own for a while and now I’m being made to feel like I’m a horrible person for not wanting to be there and now have had to cancel my own plans to go with them. I’ve already offered to help prep some of the food so it’s not like I’m leaving them short of a pair of hands but I just feel I’m going to ruin Christmas more being anti social (I don’t mean to be but it happens every Christmas Day, I absolutely despise it and there is nothing that gets me out of the mood)🙄 I’ve tried saying so many different things to get me out of it but according to him none are good enough and I’m “coming whether I like it or not”. I don’t want to sit there and pretend to be happy families when I’m not having a good time because I’m being forced to do something I have never had interest in participating in. My own family aren’t bothered that I hate Christmas I don’t see why he can’t be. I just don’t know what to do and I’m honestly debating fucking off without a word but that will probably just cause more shit😑

I just want some advice of what I can do in this situation. I’d also appreciate if you don’t have anything nice to say about me not liking Christmas then move on because it’s not like the majority of the world aren’t celebrating a religious festival when it has no significance to them.
