Have you noticed a strange shift in your partner’s routine? That gnawing feeling that something is off can be hard to ignore. According to private investigator Tom Martin, author of Seeing Life through Private Eyes, our instincts often pick up on subtle changes long before we have proof. He breaks down twenty behavioral signs that, when pieced together, can paint a concerning picture of potential infidelity. It’s less about spy gear and more about understanding the story behind sudden changes in habit and energy.
The initial signs are often the most disruptive to daily life. Martin points to unexplained absences as a major category. This includes frequent business trips, questionable excuses for missing family events, or a brand-new pattern of leaving early and coming home late. A claimed massive increase in overtime, without a corresponding work crisis or financial benefit, can also be a mask for other activities. When at home, a partner might become emotionally distant, showing less interest in physical intimacy or reacting with defensiveness to normal conversation.

The evidence often leaks into everyday logistics. Unexplained spending or hidden credit card bills can fund a secret life. You might notice mysterious purchases, like gifts you never receive or receipts for restaurants you didn’t visit. A sudden focus on appearance—excessive grooming, a new wardrobe, or an unexpected gym membership—can sometimes be motivated by a new romantic interest. Even sensory clues matter, such as occasionally smelling like someone else’s perfume or cologne.
The digital world is a common playground for secrecy. Martin highlights watch-outs like hidden or second social media accounts, coded text messages, and repeated missed calls from numbers you don’t recognize. The emotional climate at home often turns fraught. Your partner may start telling obvious, clumsy lies about small things, exhibit a consistently short fuse, or react with unusual anxiety to surprise visits, as your unexpected arrival could interrupt a planned call or meeting.
Martin’s comprehensive list is a tool for perspective, not a panic button. He emphasizes that one or two signs alone could be coincidental; it’s the combination that tells the true story. Interestingly, he concludes that the profession of private investigation is evolving. With social media, digital footprints, and location tracking often accessible, many people are now able to do initial digging themselves. However, this knowledge should be used responsibly. The goal isn’t to become a detective in your own home, but to understand the patterns so you can address concerns from a place of clarity, not just fear.
