Syag:
You wondered: “What kind of person complains about supporting their own kids?”
I wonder whether visiting in court as a spectator is possible. If so, try it. You may have a point, that a father doesn’t really complain about supporting his own children. However, the kids are, by defintion, minors, and this support money is given to their mother. That’s the rub. The man divorcing his wife is not exactly fond of handing her money.
Having said that, the Shulchan Aruch – Rema (Even Hoezer 71) I referenced earlier speaks openly about the father who is a deadbeat and doesn’t want to support his own children. This is not new.
