Infidelity is the ultimate betrayal. But does it have to be? Relationship therapist Esther Perel examines why people cheat, and unpacks why affairs are so traumatic: because they threaten our emotional security. In infidelity, she sees something unexpected — an expression of longing and loss. A must-watch for anyone who has ever cheated or been cheated on, or who simply wants a new framework for understanding relationships.
