Suspecting your boyfriend is cheating can be an awful feeling. The constant wondering, the nagging doubt, the desire to just know the truth already.

If you think he may be fooling around on Facebook, there are some telltale Facebook cheating signs to watch out for. And if those signs point to sketchy behavior, you may want to consider using a monitoring solution to get a clear picture of what’s going on.

10 Signs He’s Cheating on Facebook Messenger

While none of these behaviors automatically mean he’s having an affair, they could suggest developing emotional or physical intimacy with someone else online.

1. He’s Become Extremely Protective of His Devices and Accounts

If your boyfriend suddenly starts guarding his phone and Facebook account like they’re made of gold, it’s one of the biggest Facebook cheating signs. He used to leave his devices out openly before, but now they almost never leave his side. He could be hiding something sketchy on there.↳

2. He’s Constantly on Facebook Messenger at Weird Times

Notice him frequently messaging on Facebook at odd hours, like late at night or super early in the morning when you’re not around? Those are peak cheating on Facebook messenger times when he thinks he can fly under the radar. Consider this: why would he need to message someone so late at night when he could be sleeping or spending time with you? If this happens regularly, it’s a red flag.

3. He Gets Random Calls/Messages and Is Evasive

When he gets calls or messages that make his face go pale, and he’s extremely vague about who they’re from – major red flag. Catching cheaters on Facebook could be as simple as gently pushing to find out who that random contact is. His response could give you all the answers you need.

4. His Facebook Friend List Has Changed Dramatically

Facebook dating, a new feature for the platform, has made it easier than ever to connect with new people anonymously. It lets FB users match with one another based on interests, events, and groups they are part of. If you notice your partner suddenly has a lot of new friends that fit this description, it could be a warning sign that they’re trying to keep their options open. 

5. His Facebook Privacy Settings Have Been Ramped Up

When someone goes from being pretty open about their Facebook activity to suddenly making it a maximum privacy fort, it’s one of the top signs he’s cheating on Facebook Messenger. He could be hiding something from you specifically. Putting only a few people on your approved friend’s list doesn’t take much effort. If you can’t see his posts or pictures, it’s pretty clear he hasn’t added you to his “inner circle.” 

6. He Accuses You of Being Too Controlling or Suspicious

The classic reversal – if he starts getting really defensive and accusing you of being a controlling, overly suspicious partner anytime you have an honest question, he could be projecting his own guilt about shady behavior.

7. He’s Picked Up Shady New Single Friends on Facebook

Kind of like the friend list change, but if you notice he’s been adding a lot of new single friends on Facebook – especially attractive ones he knows in real life – he could be cheating on Facebook Messenger. Try to recollect if he’s ever mentioned these new friends or if they have any mutual connections. It could be innocent, but it’s worth paying attention to.

8. He’s Stopped Posting About You or Your Relationship

If your boyfriend was once pretty active about posting couple photos and updating his relationship status, but those posts suddenly stopped, it could be a worrying sign he’s checked out of being public about your relationship. Speaking of privacy settings (again, I know, it’s not the most fun topic!), if you’ve noticed that old posts where you were tagged together have been removed from his profile, that’s a giant red flag.

9. He Gets Extremely Uncomfortable If You Use His Device

Does he straight up panic if you ever try to use his phone for something?  It’s one of the biggest Facebook cheating signs pointing to him potentially having sketchy messaging apps or activities he needs to hide. You know how tricky it is to guess if someone will text when you’re holding their phone. That’s why he gets so anxious!

10. He Goes to Strange Lengths to Use Facebook Privately

From constantly deleting Facebook app data to using a secondary Facebook account to lying about needing to run bizarre “updates” on his device – if he’s jumping through an awful lot of hoops to use Facebook in total privacy, he’s probably hiding cheating on Facebook messenger activities.
