Mopsey,
I would just plan a dinner at your house for you and the kids.
That is about all you can control. If the kids end up at their relatives then that will be great at the time, but don't worry about it and let it ruin your holiday.
I think it's a real positive that your H wants to spend Thanks. with his family. I am sorry your son wouldn't be approving.


Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
