Other than being poor right now, my DH and I have NO money qualms. All of our issues have to do with amount coming in vs. bills going out, not whose money is doing what and consulting before we spend on stuff.
Anyway, I was going to say that our method for dividing up our funds to ensure we get a (sometimes very small) bit of play money and then enough to pay our bills is foolproof and involves continuous communication but does not end up with anybody feeling ill will towards one another. We have a joint checking/savings from which we buy food, pay bills, and do 'us' stuff together. We each have an individual account for ourselves to do with and save how we want.
The percentage we put into the joint depends on how much we are making. For example, right now I am making more steady money than my husband, so I am putting more money into the account. I generally keep the odd numbers at the end of the paycheck (i.e. the 76 dollars), and my DH will put in whatever he makes minus like 50 bucks. This is only for times like now, which is lean times and we need all the cash we can to make ends meet. When we have enough in our joint account, we each keep up to several hundred dollars from each paycheck. however, if 'we' are in trouble, than we each put whatever we have saved into the joint account to help out our household finances. Eventually, when we are able, we put that money back.
Sometimes we buy stuff straight out of our joint account, but only if we pay it back or if we talk to each other (like - omg this bag is on sale and I only have saved 75% of the cost, can we pay with it out of the joint and I will pay the remaining 25% when i get paid?)
The bottom line for DH and I is that we work hard for our money so sometimes we need to buy something nice. He wouldn't have been mad at me for buying that carryall without his permission because no doubt the week before he bought himself a new fishing rod
