My Ex-H is demanding that my kids see his mother on xmas day but they really don't want to.
They've both asked to spend x-mas eve and x-mas day with me, although have agreed to see him at his for a couple of hours on x-mas morning, to open their presents and have breakfast with him.
To make this easier for him I've invited him to watch a movie on x-mas eve with us and told him I will call him as soon as the kids get up and he can come straight round and watch them open their presents at mine before taking them to his. I even invited him to join my family on the afternoon for as long or as little as he likes. All of this was thrown back in my face.
He's now started putting pressure on me to force them into going to one of his family friend's house to see his ailing mother on the afternoon. He is telling me it is likely to be her last Christmas and I do understand that she is very ill but my kids do not want to be there.
When I tried telling them they had to go dd cried and ds stormed off upstairs and locked himself in his room and told me he didn't want to have xmas anymore.
I've convinced them to spend all day and night boxing day with him, during which they've agreed to see his mum. I've offered to go and pick his mum up and drive her to his for the couple of hours of x-mas morning they'll be there.
I'm really not sure what else I can do besides force my kids to spend x-mas somewhere they really do not want to be 
My family are very close and always have been. The kids have cousins who will be there who are as close to them as siblings, aunties and gp's who are like 2nd and 3rd sets of parents to them, they know we all be together, which is rare,even though we see each other often, it usually in small groups, rather than everyone in one place, they want to be involved in this. They don't see his family much and didn't even before they split. They've met this family friend only a handful of times in their whole lives. He is asking them to spend x-mas day with strangers.
Am I being unfair to him by refusing to make the kids go?
