I have done it, and I grew up in family owned businesses where my parents would build something then fail or sell it and go to the next thing. My personal experience has been if you two communicate well and can work together well on other tasks, then it is just extending the partnership. With my wife now she is involved in aspects of the business and does awesome things for the business. However, she doesn't want a day to day role because she likes having some separation, which honestly has really been the best for us. We work really well together because we respect each other for what we bring to the table, and for the most part we can swallow our egos. I'd say for what to watch out for: having separate time is important, having the ability to separate work from home is critical, having time set aside where work topics are not a focus etc. Respecting each others decisions and abilities as well as checking the ego is very important. I don't believe it is possible to say you can't talk about work at home etc, but you have to be able to have conversations about life outside of the job. To me that is no different than dedicating time to work out, having hobbies together etc.
