Friends of mine who are married and older, closer to retirement age, told me that they kept their accounts separate but created one joint account that was for the home. Then one of them paid the mortgage and the other one paid the bills, the electricity, the water, garbage, etc. What about splitting the bills based on the ratio of his income to your income and split the bills according to the ratio. I'm not sure if that's fair or if that would work but it's just an idea. For example, if he brings in 5K a month and you bring in 3K, that's a total of 8K. His income = 63% of the total income and your income = 38%. If the bills are 6K, then he could pay $3, 750 (63%) and you could pay $2, 250 (38%).
