There’s no one right way to navigate infidelity, whether your own or your partner’s. After 44 years as a marriage counselor, I’ve seen thousands of people make the same set of mistakes after infidelity has been revealed. In the case of infidelity, your partner is of limited value, so you need someone else. The “sex addiction” industry is primarily uninterested in sexuality in all its complexity. And it completely exonerates the Betrayed from any responsibility for creating a dysfunctional relationship, or for investigating the mess of infidelity.
