I wish she had taken me or the kids into consideration before going full-force for the custodial divorce deal. It was not good for any of us, her included.
In some twisted way, my ex-wife assumed that she was the better parent and thus more entitled to the child support, the house, and the kids' care and feeding. As a good dad, this was just her assumption. Today, her assumption wound probably be supported by state family law. But, I believe times are changing.
There are plenty of times when it's difficult not being with my kids. But what I can give them is 110% dad when they are with me. I have the rest of the time, when they are not with me, to heal and focus on myself and my goals.
My ex-wife knows I am paying and will continue to pay my child support until my daughter turns 18. She wants to keep me under the thumb of the "enforcement" of Title IV-D because hurting me gives her pleasure.
