Dr. Robin says the key ingredient to successful relationships is truth. "The truth is the light—let it shine," she says. "The truth will set you free, and that joy and balance will come when you live more in truth than in lies."

A great marriage is possible if you and your partner are willing to "show up" as grown-ups, Dr. Robin says. "You cannot be evaporated, invisible and think that you are going to create the marriage of your heart and your dreams," Dr. Robin says. "Get out of the fantasy. Let reality live and breathe and you will have a chance—a real chance—at having a great, successful and healthy marriage."
