I'm sorry too.
I agree with the others here DG - we can't change other people but we can change ourselves.
Just as we learn to dismiss the AV and it's lies, I believe you can do the same with your ex husband.
There's obviously got to be some contact because of your daughter, but I'd keep it matter of fact and at a bare minimum.
He's an
ex...for good reason.
There's no need to play into his mind games. Don't let your buttons be pushed anymore.
Counter every negative thought he places in your head with two positive ones
