....AHEM... as a wife I hope your purse strings get tied in a knot- If you don't share some of the hobbies or have hobbies that cost the same in the long run why bother at all? There's X money coming in and Y money going out hopefully leaving Z money for fun... Divide that between the spouses every month except November-December where it should be used for travel, gift, or party money. Also one other month (April tends to be good) that all money goes to replace the clothes (for both people) that people can see through but shouldn't be able too, or are full of holes, or athletic shoes that need replacing once a year. Done.
