Hey You!! Yeah You!! Uhh.. Can you pleeeeaeeee be a really nice person and answer me? kaythanksbye, ♥...?

The summer before last I met this guy at the local water park and we would hang out every time we went it was so awesome. I recognized him from elementary school but I don't think he knew me. until the day we hung out. Then the next school year I would always see him in the halls and he would be staring at me like he remembered me. Ive always really liked him and I just added him on facebook so that's got me thinking about him A LOT lately. We talk most of the day yesterday on facebook and some of the things that he said made me think that he already does like me. Since hes two years older than me and he said " but what is age but a number?" And he was flirting with me a lot but then he said "even if I'm not meaning too it always seems like I'm flirting" so that makes me rethink everything else. Oh, and he also said "Haha I dated alot of chicks back then andd I just didn't know if you had witnessed any of that" and I said "yeah you were always with a lot of girls:/" and he said "Well, that's how I used to be:) haha I was and still am a ladykiller;) but I've sorta backed off that kind of lifestyle, I'm not that kid anymore" So I know that Im not just some random girl that he talks too. And why would he just all of a sudden tell me that? Im so confused:( But I like this guy a lot and i want him to like me to! So is there anything "special" that I can do? Any thing that guys like in girls? And don't just say "be yourself" because im not planning on being anyone else:P So, does he like me? And if not how can I get him to like me? I really like him..
