I've seen other threads on this forum where an OP is "giving" their spouse and "allowance" for household expenses, and a lot of people don't think that is a good way to handle money. However, I have extended family members who would do very well on this system, as one spouse can't help but spend money that's in their hands, and I really don't think they're going to change. I think this is an excellent way to handle it, and it's good solution. The only potential problems would be mistrust over spending that "allowance". ex. A car needs a small repair and you think it's perfectly reasonable for it to come out of the $300, but she got her nails done on Monday (or whatever...I'm thinking of random scheduled frivolous expenses) and doesn't have the cash to cover it, so it has to come from the other money you're handling. Be sure to keep plenty of open communication, and I think this can totally work, and could be the best solution for your situation at the moment.
