Maybe he doesn't want to work FT - how do we know he wants this kind of arrangement? We only have 1 side of the story...
He doesn't want an arrangement in which his wife earns a third of what he does, works 4 days a week, does almost all the childcare and housework, and yet the bills are split 50/50?
I mean, I agree he should be a decent human being and start contributing half in at least some area in this relationship, whether domestic or financial, but it does seem a stretch to see him as a victim in this. If he wants to work fewer hours and do more childcare, so he's level pegging with his wife in earning power, then she's still better off: finances are still split but she has more free time. Why is his earning more money, but not sharing more, and because he earns more
But surely if he spent his own money on going out with his mates and spending weekends away like you do he wouldn't be able to pay for the holiday so you wouldn't be going away...
Erm, he earns three times more than she does, yet she provides all the domestic back-up and meets more than half the bills. I suspect he can afford all of this because, you know, he has more than double her entire salary left over as personal spends.
