“Marriage Diaries” centers around six married couples, their joys and sorrows, the drama and the rich variety of emotions they go through in their daily struggles to stay together after the proverbial “…and they lived happily ever after.” Mirrors the all-too-familiar day-to-day drama of six couples who must learn the hard way—with or in spite of their spouses—that happiness is not a goal accomplished on your wedding day, but rather the long, difficult journey that must be traveled together from that day onward.
