Should I add the guy I like on Facebook?

I need advice and help what to do. My gut feeling tells that he likes me too but I'm not sure because what if there's nothing and I just want to think he likes me too because I like him...

I mean he steals glances at me, in a conversation he keeps the eyecontact longer than it's normal, when he talks to me he's fixing his hair and whenever I pass him something he touches my hand, last time he stroked my fingers, when I said I like his pulover he was all smiley and cute.

So I don't know if he's just being nice/friendly or he likes me too and probably that's why I afraid of adding him on FB because somehow it's making the first move, right?
