The way my wife and I do it is that I (who make more money) pay the majority of the bills and also handle a lot (but not all) of the long term savings. That leaves us with roughly equal disposable income. Sometimes she asks me for a little extra cash, rarely I ask her to help cover some large sudden expense. If I'm honest, I might spend a little more than she does but she says the same about herself so it's hard to know.

This is just how we organize things though. In reality no matter who's account it's in it's all our money. We face everything in life together and recognize a single interest, you can't enrich one of us without enriching us both. I refer to it as "sharing a life."

Together we make about as much as the OP (with nothing from his wife, so a lot less overall) but I would feel a lot poorer if the two of us were scrapping over who should pay what.
