A bit radical, but it completely saved my marriage:
Split your finances completely from your wife/ husband.
I make 2/3 of the money in my marriage, my wife makes 1/3. Ergo: I pay 2/3 of the bills that come in, and she pays 1/3. Both of us contribute to our 401(k)s. The difference is, with the money I have left over, I control it (and save it) as I want. She does whatever she wants with her money. Now if she wants to buy (IMHO - too many) clothes, books, DVDs, and other miscellaneous items, she is free to do so without having to ask my permission, and we don’t fight about it. The 401(k) takes cash out upfront and assures that a bare minimum is getting saved each month and the now neither of us makes the other feel guilty. That is the BIGGEST time saver of all! No more trying to figure out the checkbook balance because one person took money out and forget to write things down…
As a side note, if one person affects a bill more than the other, that person becomes in charge of that bill. My wife makes 5x the number of long distance phone calls I do, takes longer (hot) showers, turns on the heat/ A/C more, and therefore, pays the phone and gas/electric bill accordingly. Now, when the bills are large they self regulate her bahavior since she has to pay them. Again, MUCH fewer arguments and a happier marriage overall. Whoever the person is who said marriage=merge finances should be severely beaten about the face and torso…
