I think you should stick to your original agreement, and you should fight to keep your kids in private school.

Their moving from the private environment to the public environment is not something they should be forced to endure in the middle of elementary school just because its more convenient for your ex-husband, regardless of his arguments. He is truly just trying to lighten his load at the expense of continuity in the lives of your children. I am assuming the divorce decree didn't say "until you find it inconvenient" when addressing his paying half of the schooling.

It would be more appropriate to have that discusssion when they are going from elementary to middle school, when they would be making a change anyway UNLESS they would have continued into middle school where they are now. Then I would keep them in the private school for middle school as well.

This is not meant to imply that public school is bad for your kids, but the reason for the change isn't based on what is best for them. Beware the appearance of altruism. Your ex is doing a sales job on you.
