Texas, and you are mostly correct. The people who say this are usually the ones who got full custody, no visitations, and the spouse stopped sending checks or quit their job out of spite. I've heard the remaining parent say that they'll gladly give up child support if it means that they never have to think about their ex again.
Back to the Texas part, and why you're "mostly" correct. Because it's Texas: where the wife is always wrong and the laws only protect those for whom it is enforced. Also, who are the police gonna trust? The overreacting parent who keeps calling them, or the one who always says they weren't doing anything?
"Oops, send out another Amber alert. The parent really should have said something if they knew this was gonna happen. Also, we would have been more likely to believe them if they didn't keep telling us all the time that this was going to happen."
