Christine Brown is opening up about when - and why - she ended her friendship with former sister wife Meri Brown. In her new book, Sister Wife: A Memoir of Faith, Family and Finding Freedom, Christine, 53, revealed she and Meri, 54, "fell out" nearly a decade after Christine's spiritual marriage to Kody Brown began in 1994. The plural family had recently moved to Lehi, Utah, at the time, where Christine became a teacher. "I didn't trust that [Meri] would be kind to me, particularly in front of other people," Christine wrote.
