I agree with the others.. this man is using the kids to get to you.
Addicts are chief manipulators. Your AH is worse than most because by his profession he is TRAINED to use anyone and anything in any manner to WIN. Lawyers who lose do not make good money.
So, from everything you have told us, he is using all his training and all the irrational lies that addicts use to try to WIN. He doesn't care about his children or about seeing them.. he just wants to WIN that FIGHT.
He says things to your kids to get to YOU.
My gosh.. this man really pushes my aggravation button!
