WHY IS MY BOYFRIEND MEAN TO ME INFRONT OF HIS FRIENDS? Please help :(?

[SuperDuperCatLover]

My boyfriend treats me like a princess when it's just me and him, he buys me things, tells me how much he loves me, acts all goofy and cute with me.. it's like we're not only boyfriend and girlfriend, it's like we're also best friends. I love him greatly..
But when he's infront of his friends, or mainly on social networking sites, he acts different from me, he kind of insults me, trys to make me seem stupid and shrugs off anything nice I say around him. If he's out with his friends he'll ignore me, and he'll pick up his friends habits too.
It seems like he thinks he's too 'cool' to be nice to be a gentleman infront of his friends.


** Once, his friend said "Guys who are soppy and cute on Facebook or Twitter make me sick"
So, I'm guessing it's his influence too.

Please help guys
