Psychotherapist Dr. Shirley Glass
discusses "the new infidelity crisis." She's studied extramarital affairs since the mid 1970's and has written a new book called "NOT Just Friends: Protect Your Relationship from Infidelity and Heal the Trauma of Betrayal." She says that the workplace has become the new breeding ground for extramarital affairs. GLASS is, by the way, the mother of Ira Glass, of public radio's "This American Life."
