Generally speaking:
I feel like guys don't care if their girls "emotionally" cheat, but will get pissed if they "physically" cheat. And from the gender of the authors of articles like this, it appears the opposite is true for women.
Again
Generally speaking. Generally. As in the aggregate stats of each gender, doesn't mean there are no exceptions to the rule. Put pitchforks down please. I'm just an innocent human being who wants to type things.
