I know. It's hard to believe. But a recent study from Penn State has uncovered that way more guys than you'd expect find emotional betrayal a bigger deal than sexual infidelity. Yes, you read that right. We are talking about MEN here.

Popular belief until now was that women suffered the crushing blows of an emotional affair much more than men, who considered you getting it on with someone else a Class A offense. It all goes back to evolution: Men learned that they had to be vigilant about whom you had sex with because they could never really tell if a kid was theirs, while women sought an emotional connection with a guy who'd commit to sticking around and raising them.

According to the study, this theory still holds true, but it's not so black and white. In fact, a man's personality (rather than his ego) plays a bigger role in how he experiences jealousy. The researchers found that men who were secure in their attachments to women -- i.e. not commitment-phobes -- were more likely to get jealous over emotional infidelity. In other words, we're talking about men who basically think like we do. Now we just need to find them.

What would hurt you worse: His having sex, or cozying up to someone else emotionally?
