Why People Cheat: The Psychology of Infidelity, Guilt & Healing After Betrayal

Infidelity is one of the most devastating forms of betrayal—but why do people cheat? Is it always about love? Do people who are unfaithful actually feel guilt and remorse? If they do, how long does that guilt last? And perhaps the biggest question of all: Can a relationship truly heal after betrayal?

In this episode of The Dr. Sarah Hensley Show, Dr. Sarah Hensley explores the psychology of infidelity through the lenses of attachment theory, neuroscience, trauma, and relationship psychology. Rather than offering simplistic answers, she examines the emotional, psychological, and relational factors that contribute to cheating, what genuine remorse looks like, and what it actually takes for couples to rebuild trust after betrayal.

Whether you've been cheated on, struggled with infidelity in your own relationship, or simply want to understand why it happens, this episode offers evidence-based insight, compassion, and practical guidance. In this episode:
