Never put your husband down in public or in front of the kids. Never put your business on the street. Your personal affairs need to be dealt with together and in private. Keep your eyes open. Don't get in a rut.
More marriages fall apart due to plain old boredom than anything else.
Even if you are a natural born matriarch, resist the temptation to manage every aspect of your husband's life. He already has or had a mother and he doesn't need you to back her up. Be you husband's friend. Be like the Proverbs woman. Do your husband good and not evil all the days of his life.
