I am not a guy, but here's my take on the question. We have (and always have):
1.) "House money" encompasses the household checking account, the savings account, HSA account, IRAs, and investment accounts. We each contribute to this on a weekly basis. Any withdrawals in excess of basic bills are discussed (see below). I believe that because we handle our money this way we rarely argue about it and can pretty much have whatever we want within reason. We switch off the responsibility of reconciling the accounts so we're both in touch and familiar with the balances and the fluctuations in them.
2.) "His money" is his checking account and his savings account.
3.) "My money" is my checking account and my savings account.
The latter two are our personal funds, we may do with them whatever we wish. He just bought a new electric guitar, I had two file cabinets powdercoated and two tools made for the woodstove in my studio. I think having "your own" money is a wise and healthy thing. We think it's kind of weird that a couple of our friends "get an allowance" and have to "ask" their spouses for money for something like clothing, but if they're happy with the arrangement who are we to question it? NO WAY we'd ever live that way, however.
A funny aside; several years ago the husband was real hot buy a splitter. I was hesitant but grudgingly went along with the "hare brained scheme". The last laugh has been entirely on me. Last year I'd finally had enough when it took me 25 minutes to get the 25 yr. old, 24" gas range to hold 350 degrees so I could make a cake. While it cooled I went to the store and purchased a brand spankin' new GE Profile gas range and arranged to have it installed. He was stunned and skeptical. Until he used it the first time, lol. I married a really smart man who is as thoughtful as I about spending money. We make a good team.
