After 10 years of marriage to a terrific wife, we've had our problems but money hasn't, thankfully, been one of them.
Budgeting is key - we both have wants, and our family has needs. We have three kinds of money - OUR money, MY money, and HER money. Take the time to figure out how much of your household income goes into each, and
stick to it . Separate accounts for each helps. Adjust the amounts as your total income changes. If you don't have a lot of play money, it's tougher, but still workable.
Stuff thats just for you? Spend your money, when it's gone,
you're done. Same for her.
Treat credit the same- don't use a joint card to buy that new custom folder, it's tough to justify how that benefits your spouse, unless you pay the bill with YOUR money.
The joint expenses - gas, kids college, rent/mortgage, groceries, kids allowance -comes from the OUR money. The HIS and HER money is for toys, and stuff you could probably live without but make life more interesting - like knives.
It takes some math, and some discipline, but if done right its tough for either of you to complain about what the other bought.
