I wish good luck to all involved with this company. I am not sure if it's a good idea to work so closely with your fiance/wife/husband in a start up. If things don't work out, there will be more than a job that's lost.
While I can see hedging your bets by having your spouse work a normal job (and possibly get you on their health insurance), if a failed startup is going to doom your marriage, your marriage is already doomed.
