Cheating Stories: 'Vow' Author Wendy Plump On Marriage And Infidelity

In a recent AOL "You've Got" interview, writer Wendy Plump spoke about what she learned about monogamous relationships after ending an 18-year marriage marred by infidelity.

"I would advocate for a less black-and-white harsh condemnation of infidelity and more of a 'let's see how we think about it in case it happens to us' [attitude]," said Plump, whose book, "Vow: A Memoir of Marriage (and Other Affairs)," hits bookshelves on February 13.
