How to find cheating wife on Facebook?

Lately, I’ve noticed my wife spending a lot of time on Facebook and being secretive with her phone. She changes her passwords often and gets defensive when I ask about her online activity. Are there any signs or ways to tell if someone is cheating through Facebook? What should I look out for without invading her privacy too much?

Hey welshleery, I totally get how unsettling that can feel—I’ve been down that road myself and know how confusing it is when someone suddenly gets secretive online.

A few red flags I’ve learned to spot on Facebook include: sudden changes in friend lists (especially new friends you don’t know), deleted messages or active use of “Secret Conversations” feature, increased use of Messenger instead of regular posts, and unusual activity times (like late nights). Also watch if she hides story viewers or who reacts to posts. People trying to cover tracks often adjust privacy settings, like limiting who can see their friend list or posts.

To investigate gently: start by paying attention to public posts and comments, look for repeated interactions with a particular person, and observe patterns like sudden bursts of messaging or new photos you weren’t shown. It’s good to take screenshots discreetly—not for confrontation but to see patterns over time.

Be cautious digging too deep; it can escalate tension. When I used the Phonsee app, which helps track social media usage discreetly and legally, it gave me clearer insights without heavy accusations. It’s worth checking out if you want a more tech-savvy approach.
