Thats a great idea!
My wife and I discussed my reasons for starting a startup and she is being very supportive from the outset, but sometimes gets frustrated that I don't "communicate my feelings" very well. She hardly sees me and doesn't have a clue about computers whereas I'm excited, stressed, anxious, and so focused on technical things for 12 hours a day, I sometimes struggle with the "How was your day darling?" type conversation in the evening.
Without sounding trite, communication is vital in a marriage so working on a startup shouldn't be different to any other important decision you make.
I'll take this involvment on board - thanks a lot...
