Most Helpful Guy
it's fine as long as it's just kissing his butt cheek like you said.

First of all, he's doing the cheek-kissing, but then posting the pictures of the cheek-kissing - wtf? This is just so juvenile. I doubt he's actually doing anything with these girls but he's definitely being a showboat, showing off to friends that he's attracting girls and no private message to you to put insurance on this kind of frat boy behaviour is going to fix that. He's just not thinking of how something will make you feel, and seems more concerned about how he'll appear to friends. I would send him a message to stop it, and take the pictures down if they are making you unhappy. Like I said, I doubt he's doing much more. Real cheats usually try hiding their behaviour, and he's just showing off that he can flirt.
