My husband turns all of his money over to me and I handle the money, bills, investing. He wants nothing to do with it, just isn't interested. If he wants something, he lets me know and I save up for it, or give him the go ahead on purchasing it. Aside from our family savings and checking, we also have our own bank accounts and I transfer money into them when I can so we have our own spending money.
We are both respectful of what the other one wants and we both try very hard to make it happen. If I want something that is expensive and haven't gotten all the money saved up, he will offer to give me his spending money--and vise versa. It works out for us.
