re: Who wears the financial pants?

Same for us. My wife (no pics) is very engaged in all financial decisions. She does most of the shopping for the household. Most of the day-to-day stuff - bills, taxes, budgets, investment decisions, etc is handled by me. With one notable exception: I am a commodities trader, and I have handed my P&L over to her to manage. This keeps her engaged and brings an additional level of accountability, there are a few other reasons but those are the primary.
It is a partnership above all.
