In business you're going to have to make some decisions were you will disagree with each other. Unfortunately this will carry over to your personal relationship. Personal to business disagreements will also happen. If you can, avoid putting extra stress on your marriage. It's hard enough to stay married in general. You can say the same thing for the business. Also, it's nice to remove yourself from the stress of work. It's going to be so much harder when your wife is going thru the same stress.

In short, don't do it. It's not worth the extra stress.
