Marriage is not a business relationship.
The problem is, you’re not in a purely business relationship. You’re the man’s wife. Now, contrary to popular opinion, perhaps, men don’t want to keep the “little woman” sidelined at home. If a wife is a smart, capable woman, most men want her involvement, ideas, help, and so on. The problem is, that is a secondary desire. In my research it was clear that what a man most needs from his wife, at all times, in all seasons, no matter what else is going on, is something quite different: he needs a cheerleader. A completely solid support. Someone who believes in him when he doesn’t believe in himself, and says “I know you can do it!”
