I'm moving down to be with my fiancee in December, so one way or another we are going to have to run some joint finances. Until I get another full-time job, she will be the main breadwinner, but we have fairly even earnings potential once I find work. She also has two children and most of the assets (stop sniggering at the back), which will obviously spice up the financial mix somewhat.
What has worked for you when doing this and why?
