Is he really into me or just being a flirt?

Ok so a guy i'm friends with at work (don't worry for those of you who've seen my previous questions diff guy lol) and he's very charming and always compliments the girls at work on how they look and lightly flirt with them, but he always gives me hugs, or will come up to me and say ';hey beautiful,'; or ';hey sexy';, ask how my day is going. and one day i jokingly said ';oh you miss me when i'm not around'; and his tone changed and he said ';yeah, alot more than you'll ever know.'; and than he walked away, or a mutual friend of ours kyle came up and gave me a hug, in front of the guy i'm into, and the guy kinda stiffened up, and kind of wrote him off when kyle said hi to him. kyle says he never does that when kyle hugs a girl in front of him. A few more examples (i'm almost done i promise lol) whenever i dont' hug him first he'll smile and say ';oh, come here!'; and hug me, he also will put his hand out like he wants a high five, but he'll just hold my hand for a minute until i let go, and one time he rubbed the inside of my palm with his finger and said ';Doesn't that feel weird?'; and i said ';not really'; and he said oh, did it for about two more seconds than stopped, or when i joke around about him driving me to somewhere really far, he'll get a lil serious and say ';i'll drive you any where you want to go';. So what do all these things mean? Is he just being a flirt, or is he into me? or what? lol i'm confusedIs he really into me or just being a flirt?

It sounds like he is into you but he is just naturally flirty with everyone. Its kind of a hard call as he flirts with the other girls too.
