Betrayal Trauma with Dr. Jessica Lamar

Last interview, we sat down with Tamara Cooper to discuss compulsive sexual behavior. The question remained: what happens to the partners after betrayal? So this week, we sit down with Jessica Lamar, CPTT (Certified Partner Trauma Therapist) for an eye-opening conversation on betrayal trauma—the profound impact of infidelity and sex addiction on partners. Jessica brings years of clinical expertise to the table as we unpack the difference between sex addiction and infidelity, explore the trauma responses that often follow discovery, and discuss what healing actually looks like. If you've ever wondered how to support someone reeling from betrayal—or how to recognize unhealthy patterns masked as "normal"—this interview is a must-listen.
