I bet if a guy decided after a divorce to downgrade his job to one that paid less, she'd be the first one to scream about impugned income and what he 'owes' his ex-family in terms of support.
She's probably jealous, like a lot of women, that the way men are raised means when they get a shit sandwitch they don't sit around complaining about it, they do something with it.
I've heard guys who've had their wives(who were alcoholics or otherwise problematic) just up and quit--disappear from their lives completely, no money, no contact--who said they were grateful for it because it was one huge burden out of their lives and they could now concentrate on taking care of their kids. Without monetary support from the ex, I might add. Which they didn't even whine about.
How is it that single fathers manage to raise kids, work and deal with life by themselves with almost no support but for women it's a constant source of whiiiiiiiiiiiiiiine?
