how do you think he will respond if i tell him i like him?

For a while he seemed into me, we kissed/hungout a few times, but our little fling fizzled out quick and im unsure why. He just suddenly stopped making an effort to hang out with me. Now when we see each other around, we make brief polite conversation but that's it. Sometimes I see him flirting with other girls. My friends say he's just a jerk and i should get over him, but i still really like him. It's like he's taunting me: liking my profile picture on facebook, greeting me with hugs, being friendlier than ever, but still doesnt text me. Its been 3 weeks since we last hung out. I want to find out why. I wonder if maybe he's just a player.

This weekend im planning on discussing this with him, ill probably end up running into him at party, and maybe i can just pull him aside somewhere quiet and ask him what the deal is. I want to tell him i have a crush on him and find out if he feels the same. But im afraid of making a fool of myself, what if he never thought anything of me and treats all girls the same? I dont want to come across as clingy and obsessive but im desperate to find some closure and see whats on his mind. How should i ask him, how do you think he will respond?
