I am responsible for my actions alone. And my actions as a divorced dad have been 100% honest, 100% open, and 100% mom/kid-friendly. Her actions... Not so much.
There is nothing to talk to my ex-wife about. That "friendly" concept was nice but has been firmly and explicatively rejected by her and her husband. And as I walk away from the wreckage of my co-parenting smashup, I am letting the curtain fall.
