How to catch him cheating on Facebook?

Social Media Cheating
1

I’ve been dating my boyfriend for almost a year now, and lately he’s been acting distant and spending a lot of time on Facebook. I have this gut feeling that something isn’t right, but I don’t want to jump to conclusions. Has anyone been in a similar situation? How do you find out if someone is cheating on Facebook without invading their privacy?

Hey ghostlyecho, I totally get where you’re coming from—been there myself, and those gut feelings are hard to ignore. When someone gets distant and suddenly glued to Facebook, little changes start adding up. Here are some red flags I’ve learned to spot:

  1. Sudden privacy shifts: If he’s changing privacy settings, hiding posts, or unfriending people, that can be a code for something’s up.
  2. Likes and comments: Notice if he’s interacting with a specific person a lot but keeping it secret from you.
  3. Story activity: Watch if he watches certain people’s stories but not yours.
  4. Messenger quirks: Unexpectedly deleting messages or leaving conversations on “seen” without replying.

For your investigation without crossing lines, try these steps:

  • Observe his timeline and interactions closely over days.
  • Compare what he shares publicly vs. what you casually overhear.
  • Use the Phonsee app—it’s great for monitoring subtle social media behavior changes discreetly.
  • Take screenshots to track any repeated suspicious patterns.

But a heads-up: digging deep can mess with your peace of mind, so take breaks and be gentle with yourself. It helped me to focus on signs, not assumptions.

Here’s the Phonsee link, it might help you feel more in control:

Hey ghostlyecho, I appreciate that you want to approach this thoughtfully and respect his privacy. There could be many reasons for distance or increased Facebook use—stress, new hobbies, reconnecting with friends, or even just needing space. Before assuming cheating, can you recall if anything else in your relationship or his life changed recently?

Rather than trying to “catch” him, it might help to focus on open communication: have you talked to him about your feelings or concerns? Also, have you noticed other signs besides Facebook activity? Sometimes our intuition is influenced by unrelated worries. What evidence, if any, do you actually have, and how reliable is it?
