Cliche- does he like me (one of those flirty guys)?

So there's this great guy at my school who I hang out with a lot. He has dirty blonde hair, a pretty smile, and is smart, funny, athletic, competitive, and nice. The only thing is, he's a really flirty guy, and hangs out with all of the girls. With him, it's completely normal to walk around holding hands, or to put your arms around each other, hug, whatever, and a lot of girls do that with him. At our school it isn't that weird to have physical contact like that without being more than friends, but usually guys keep their distance. A ton of girls like him, because he is just the flirty guy who is sweet to all of them. I don't know if he likes me or if I am just another girl- he'll always leave his friends and sit with me, go out of his way to talk to me, walk with me in that way where you lean up against each other casually, and he's really sweet and nice. He is protective- there are other guys like that and he'll always complain that they're such players after they leave from hanging out with me. Do you think he likes me, or am I another girl and he is a total player? And do you think it's even worth considering him because he's so flirty?
