Surprised because in the OP it read (to me, and consider the source, I have ADHD, and don't always catch the details....) like you were co-parenting as a unit... I read it like this was a conflict in your home, a decision that had been made by a dh, not an ex, kwim?
It's hard when you put work into parenting one way, and the other parent isn't co-parenting with the same basic model. I'm sorry.
