I often pontificate that my ex-wife is angry because she didn't get the happiness she imagined by moving her cheese from one man to a different man. She got everything she wanted in the divorce: the house, the child support payment + insurance for the kids, and the 70/30 parenting schedule, and still she's not happy.
My ex-wife is pressing me for money, not because she needs it, not because she thinks my son needs it, but because her brain is wired to think about money first, before all else.
We've been divorced for over eight years. Our son has just turned 18 and is heading to college next year. We're not really co-parenting, but our kids are doing just fine. And as they grow older, they are seeking a renewed relationship with me.
When one parent checks out their options for divorce, they are beginning the process of separation and exit from the relationship. And hey, if they like the divorce brochure the attorney lays before them, they might even start leaning into divorce.
