He is such a snake. I knew he was going to start pulling this. I can't imagine what the kids are saying/thinking as he does these things.

Can you get a emergency court ordered visitation schedule? Because it sounds like you don't have anything "in stone" for this time. YOu need to or he will continue to pull this and will always have reasons to back himself up. And, with a "in stone" schedule you won't have to contact him. I've heard of notebooks going back and forth with the kids as well (with numbered pages) so that you can communicate there and it can also go to court if need be.

I'm proud of you for not being a doormat, Karen. Let him dig himself a grave. Time for him to realize that you will ALWAYS do what is best for the kids, and you will NOT agree to all of his cr@p.
