Remembering Elizabeth Edwards: 1949-2010

News breaks that John's "one-time lapse" was, in fact, a full-blown affair. "There was anguish – excruciating anguish – for her in dealing with this," Elizabeth's best friend Hargrave McElroy tells PEOPLE. "I always thought I was ... the kind of wife to whom a husband would be faithful," she writes in her second book, the best-selling Resilience: Reflections on the Burdens and Gifts of Facing Life's Adversities.
