How to catch someone cheating on Facebook?

I’ve been in a relationship for a couple of years now, and lately, my partner has been acting distant and spending a lot of time on Facebook. I’m starting to get suspicious but don’t want to jump to conclusions. Has anyone here dealt with something similar? What are some signs to look out for, or ways to find out if someone is cheating on Facebook?

Hey amberleafvibe, I totally get where you’re coming from. I went through something similar when my ex suddenly got secretive on Facebook, and it’s heartbreaking but also super confusing.

Typically, watch for subtle shifts like deleting messages, turning off their “Active Now” status, or suddenly being protective of their phone. Check if they start liking or commenting on posts from people you don’t know, or if they have new friends showing up quickly without explanation. Also, be aware if they start using Facebook Messenger in secretive ways—like switching to disappearing messages or deleting conversations regularly.

Here’s a step-by-step that helped me:

  1. Look for consistency: Compare current Facebook activity to their normal patterns.
  2. Notice privacy changes: If they suddenly change privacy settings to hide friends list or posts, that’s a red flag.
  3. Check mutual friends’ activity or comments for hints.
  4. Observe Instagram linked to Facebook for story interactions if available.
  5. If you’re tech-savvy, apps like Phonsee can help monitor digital footprints discreetly (just proceed carefully emotionally).

Be prepared: digging can be stressful and may confirm fears you weren’t ready for. Emotional support from friends or a counselor helps!

Hey amberleafvibe, I’ve been through a similar painful situation. My ex was distant and hiding his phone activity, which I later found included secret chats and profiles. Here’s what helped me: look for sudden privacy changes on their Facebook, secretive phone behavior, or deleted messages. But beware—digging too hard often causes more pain or destroys trust beyond repair. Instead, focus on open conversations first. If your gut keeps nagging, consider direct talks or even counseling rather than spying. Protect your well-being—sometimes suspicion reflects deeper relationship issues, not just Facebook activity. Keep your boundaries clear, and don’t lose yourself in the search.
