To meet her boyfriend of a few month's kids for the first time on Christmas day?
The children are 19-23 years old.
I know my ex h is a dick for this as he's invited her to his parents house without discussing it with our children but I think it says something about her that she's going along with it.
The children aren't interested in meeting her or knowing anything about her. They'll go to see their grandparents and put up with him and her.
This is the latest thing on a long long list of despicable behaviour from him since the end of our marriage. He has no idea of huge things that have been happening for the children this year. He barely calls them, I can't remember the last time he saw them.
So Christmas Day afternoon I'll be home on my own for a bit, which is fine, but it's hard to take that they'll be with my children. Getting to joy of seeing them when ex h does fuck all for them. She has none of her own, she's divorced then widowed and wasn't the OW.
