I hate to cast aspersions on another dude, especially because I know that suspicion can ruin a relationship faster than juicy chili farts, but worry might not be totally out of the question.

Being on Facebook can be incredibly liberating, like another version of our life where our interactions are quantized and we know exactly how many friends we have and which Jonas Brother we most resemble. But liberation can lead to unfortunate decisions, wandering clicks, even some guilty feed tampering.

The good news is, Facebook is plenty addictive in its own right, so there's no need to jump to any conclusions right away. Your boyfriend could easily just be on there playing Zombie Mob Ninjas or something for hours at a time.

And even if he is contacting some exes, that could be harmless flirting, a little digital ego booster, or something more serious. I'd guess most guys who are guilty of spittin' game on the 'Face would never act on it in the real world. There's a lot of distance between flirting online and bumping uglies in a parking lot. My point is not to go in guns blazing and risk looking like a n00b when it turns out he's been a good boy all along.

But I can't tell you guys don't use Facebook to flirt, because we do. It's so easy; like pressing a button that says "Flirt." Then in little parentheses it says "Remember? I'm that guy from your high school, like a year behind you. No? I lost weight."

If it's stressing you out, tell him about it, but do so in a way that's not going to make him defensive. The specifics of that maneuver I'll leave in your much more qualified hands.
