D..
Your attorney is right. Remember, the financial settlement affects her GREATLY, as it also affects you. He is trying to blackmail you into giving him what he wants. Don't let him. You and your daughter need the money for the future. Do what you are supposed to do, and document, document, document. Has your lawyer told you to only communicate by email or text message so what he says is recorded for the court? Ask about that. I don't think I would speak to him at all, but tell him that he has to write from now on.
If you have a good lawyer, perhaps they could get him for kidnapping if he takes her somewhere during the part of the summer he can't have her.
Say nothing to him without the expressed agreement of your attorney.
Good luck,
Dawn
