“I’m a reform cheater,” Dr. Emily Morse confesses early in this episode, and that admission sets the tone for a conversation that refuses to moralize. Instead, she and co-host Dr. Scott Lyons, a somatic trauma psychologist, walk through the messy, subjective reality of infidelity — what counts, why it happens, and what repair actually requires. The central insight is deceptively simple: most couples never define what cheating means to them, and that silence is the real breeding ground for betrayal.

Cheating is subjective — and couples rarely talk about it

The episode’s core argument is that there is no universal definition of cheating. “It’s actually subjective,” Morse says. “It’s nuanced for sure.” For some people, porn use is a violation; for others, it’s a non-issue. Emotional intimacy with a coworker — the “office wife” phenomenon — can feel like a deeper betrayal than a one-night stand. Even dreaming about someone else has ended relationships. The problem, Morse and Lyons argue, is that most couples enter monogamy with unspoken assumptions: that attraction to others will simply stop, that porn will disappear, that no ambiguity will ever arise. “I think part of this lack of communication is what leads to the highest statistics on cheating,” Morse says.

Show Notes

Let's talk about where the line actually is when it comes to cheating… because most couples never have this conversation until it's too late. In this episode I'm sitting down with licensed holistic psychologist and trauma expert Scott Lyons to unpack what cheating really means in the digital age, from liking thirst traps and DMing an ex at 2am to full on affairs and everything in between. I'm also sharing something I've never talked about publicly: I'm a reformed cheater, and I'm getting honest about what was really going on underneath that.

Whether you've been cheated on, done the cheating, or just want to get ahead of it before it becomes a problem in your relationship, this episode gives you the real talk, the research, and the tools to define your boundaries, rebuild trust, and have the conversation most couples are too scared to start.
