We work out our finances like this: Each person pays out the same % of income towards the bills. It obviously means they aren't split into equal amounts, just equal percentages. We went through a few times where one of us wasn't working so whoever wasn't able to contribute financially, did ALOT if not all of the household chores. It worked for us. We each keep and maintain seperate accounts, for our own personal payments or spending money.
We have found also that C works very long hours(about 80/wk), T about 60/wk and I work about 30/wk, so I do a big part of the household chores, and I really don't mind. I would never expect either one of them to have to come home after long hours to a mess!
