we've been divorced since 2004, separated 2002. I dutifully read every book about how to co-parent so children are least affected by divorce. For him, it was just a mean, hurtful contest for I don't even know what. I was so naive that I kept believing he would eventually settle down for the kids' sake and just co-parent like normal divorced parents. I STILL make every effort to co-parent via email or calm conversation, I am a fool, lol. If it hasn't happened in 13 yrs, it is never going to happen. He's educated, totally capable of grasping the concept of co-parenting, he just keeps up a battle that none of us win when you come right down to it. It's sad.
