Too risky. Most of the time the business fails and a summons for divorce and bankruptcy comes right along with it. The return is not worth the risk.
My wife is a M.D. I have my own company with 10 partners from the same MBA school. Makes much more sense. She supports me and I support her.
I showed her the business plan and we talked about risks and how I could use her help to throw a bucket of cold water on me if I get too close to the fire. She is a very loving Chinese wife. She has her practice and I listen to her and care for her feeling in front of the business. It can wait. 2 hours won’t kill me. But it is a bit hard and takes mental discipline because I want to be thinking, working, and growing the business 24/7/365 every day, all day, each day. worldwide. I cannot do this. Family first. And a few hours a night and taking her on dates on Saturday day and night is important for both of us to maintain intimacy and lower the risk. I would rather lose the business than my wife. She has needs too and has a stressful career. Surgeries that result in no help and the death of a patient. Cancer treatment that doesn’t quite get there. And the joys when her help wins life for the patient. I always smooch her and cook her dinner. This is so important. I don’t believe it is worth it to start a business with a spouse. The lines get blurred. Sure it MAY work, but the odds are very low. It is a multicollinearity problem folks with subtractions from economic rent by damaging the relationship.
