I am so in awe of you. I don't know that when it came to my kids I would have kept my mouth shut but the way you handled it was absolutely the right way. What are these ex's thinking? Isn't it enough that our kids have to mourn for their family as they knew it without throwing them into an uncomfortable situation that they have no control over? He's their Father for goodness sake but he sure isn't acting like one.
Honey you're lawyer will handle things according to the decree. He shouldn't have signed it if he wasn't going to abide by it, but he did and there are consequences. I'm dorry that you're going through this and I wish there were more I could do.
