Mark Sanford Took 'Faithful' Out of Vows: Jenny

Jenny Sanford shares her story of a "cheap" husband who insisted on taking the word "faithful" out of their wedding vows, telling Barbara Walters that despite it all, "I thought he loved me in his own way." In a 20/20 interview airing Friday, Sanford calls her marriage "not a fiery romantic marriage, necessarily, but a very good, steady, solid, supportive marriage"—though her husband never called her his soulmate, as he did his mistress.

Sanford details just how frugal her husband was, once giving her—and then taking back—a diamond necklace. But the worst moment came after discovering the affair, when Mark begged her to let him see his mistress one last time. "It never occurred to me that this person I knew, who was actually a fairly grounded person, would be asking me something so morally offensive," she says. "I mean, who, who gives their spouse permission to go see their lover?"
