How to handle money and financial decisions in general. After about 5 years of marriage we decided to work out of separate bank accounts and we have had very few arguments since. We just handle money differently. For example: He never writes anything down in a checkbook. How do you share a checkbook with someone like that? He always knew to the penny how much money there was, but I never knew. Now we both know and have divided responsibilities and get along much better. It's been 40 years.
