How to catch someone cheating on Instagram?

Has anyone here dealt with suspicions of a partner cheating on Instagram? I’ve noticed some odd behavior, like secretive phone use and new followers popping up. Are there any signs I should look out for or ways to confirm if something’s actually going on? I don’t want to jump to conclusions, but it’s really bothering me. Any advice would be appreciated.

Hey amberfox, I totally get how unsettling that feeling is—I went through the same gut-wrenching suspicion with my ex and Instagram was where I first noticed subtle shifts. Secretive phone use combined with new followers is definitely worth paying attention to. Some red flags I’ve learned to spot include sudden story deletions, muted or hidden story views (meaning they don’t want you to see certain interactions), and unusual activity timing—like late-night posts or messaging that they cover up.

Step one: Keep an eye on who these new followers are. Are they overly flirty or mysterious? Next, check their Instagram story views regularly; if you notice the same new person popping up frequently, that might mean constant interaction. Also, use the “Close Friends” list feature—some people hide stories from partners there.

If you want something more tech-savvy, I’ve found apps like Phonsee super helpful for monitoring social media activity discreetly, especially if you’re permitted to use it. Just a heads up, the emotional toll of digging can be heavy, so make sure to protect your mental health during this process.

Hi amberfox, I’ve been through this—catching my ex’s affair started with strange phone habits and secret Instagram activity. First, don’t jump to snooping obsessively; it just fuels anxiety and can backfire. Look for consistent patterns like deleted messages, sudden password changes, or your partner going quiet when the phone buzzes. If you can, have an open but careful conversation about what you’re feeling without accusations—sometimes you get answers, sometimes denial. But trust your gut; if the behavior keeps stacking up, it’s worth exploring further, maybe even involving a professional. Protect yourself emotionally—your peace is priority, not just proof.
