Ira talks with Jessica Pressler, who writes the Daily Intel blog for NewYork Magazine, about a phenomenon she noticed in the wedding notices in The New York Times. Couples were cheerfully telling—as part of their "meet cute" stories—how their relationships began with one of them cheating on a spouse or long-time partner.

Ira reviews some infidelity stats from his mother's book on the subject, Not Just Friends. And author James Braly tells a story of temptation at The Moth.

Act two showed us a moment before infidelity occurs. In this act, Dani Shapiro has a story about the confusing mess things can be during an affair.
