Ali Marsh, a private investigator specializing in infidelity cases, says one of the biggest giveaways is what cheaters talk about. While people often think catching cheating requires snooping or surveillance, Marsh highlights that the key is often in conversations.
When someone is emotionally involved with another, they frequently mention that person indirectly—even if socially or morally they’re not supposed to. Typical phrases like “So-and-so did something today” reveal their preoccupation.
This shift in communication is usually paired with changes in behavior—being less emotionally invested or acting differently toward their partner.
Psychologist Elena Touroni adds that cheating is often not a one-time event, with underlying emotional factors like low self-esteem playing a role.
The best way to spot infidelity could be paying attention to how your partner talks and the subtle clues they reveal.
