Deb says a year ago, she discovered her husband, David’s, tangled web of lies and sexual affairs that spanned more than a decade and she believes he’s cheated on her at least 1,000 times. David admits he had several inappropriate relationships with other women, but claims he only had two physical affairs, and he’s ended it all. He says Deb’s obsession with proving he’s still unfaithful is destroying their marriage. Can this relationship be saved?
