Whitney and Mason's life is perfect. When Beth explained her Seven Year Theory. They scoffed at the idea of the seventh year of marriage being the make it or break it year for most couples. That theory didn't apply to them. They were the perfect couple. Their brand new house overlooked a spacious lake. Their brand new cars were state of the art. Their careers were taking off at an accelerated rate. Their sex life was incredible. Their lives were perfect. Mason considered himself incredibly lucky to have a wife like Whitney. She was beautiful, sexy, smart, had a professional attitude toward life and she wasn't interested in starting a family. When Whitney's widower brother-in-law was killed leaving his three small children in Whitney and Mason's charge, Mason is exposed to a new side of Whitney. A side he was not prepared for, a side he never thought he'd see. Suddenly Mason's world was filled with diapers and stains. His perfectly coiffed wife quickly transformed into an unkempt mother of three living in jeans and carrying a diaperbag as a purse. Mason's needs were no longer being filled. His house was a noisy mess. There was a 6 year old boy looking to him for fatherly attention. But fatherhood requires a man to live for his children and not himself. Mason was not prepared to do that, but how could he walk away from Whitney in her hour of need?
