Infidelity can be one of the most painful experiences in any relationship—and for many, it can also become a turning point. In this episode of Sisters in Sobriety, hosts Sonia and Kathleen unpack what it really means to stay emotionally sober through betrayal, heartbreak, and healing. Drawing on their own lived experiences and Kathleen’s clinical expertise, they’ll help you understand not only why infidelity happens, but how to navigate the emotional fallout with clarity, self-compassion, and growth.

Together, they explore questions many of us have struggled with in silence: What counts as cheating? Is emotional infidelity just as damaging as physical betrayal? Can a relationship ever truly recover from deceit? And how do alcohol, secrecy, and unmet needs complicate our choices—and our healing? From defining betrayal to understanding why it feels so personal, this conversation offers both insight and empathy for anyone who’s been on either side of infidelity.

Listeners will learn how infidelity impacts emotional sobriety, the difference between emotional and physical affairs, and how alcohol can blur—but never justify—boundaries. Kathleen breaks down the psychology of betrayal, explaining the roles of trust, attachment, and validation, while Sonia opens up about her own experience of infidelity and what it taught her about resilience, self-worth, and the power of sitting with discomfort. You’ll walk away with practical insights about rebuilding trust, recognizing red flags, and understanding when it’s time to rebuild—or let go.

Finally, Sonia shares a deeply personal story about the aftermath of her own betrayal—the shock, the anger, and the white-knuckled early days of staying sober through grief—while Kathleen reflects on what it takes to heal, whether together or apart. Their raw honesty and humor make space for reflection, laughter, and growth, even in the messy middle of heartbreak.
