When one of my businesses took a major nosedive in 2003, my wife worked for me, she did the bookkeeping while I tried to keep the business alive (successfully, in the end). We fought a lot, but I have always appreciated that time -- I think it was a big help to our relationship for her to understand some of the ins and outs of business life. We also have 'overshared' about business; for a few years of my life in a previous startup, she put in 3+ hours a day talking / planning / processing with me. That was not a good plan for us; my (unsolicited) advice: have some outside-of-work hobbies with your co-founding spouse so that end-of-job for one of you does not equal end of relationship.
