Every time I see him, my heart skips a beat?

I'm just your average teenager. Sort of. I've seen this guy who's in my lunch period and he is so cute. In the hallways, he's always in a different place, so when I see him I'm surprised and my heart beats faster and skips a beat. I don't know if my face goes red or not, most likely.. I don't know what to do! I don't know his name, I don't know if he has a girlfriend. Although, he talks to girl that I know. She was in my math cl and she stuck something long in her pants and it was really inappropriate. I'm not rude, I just don't understand, if he does, why he may like a girl like her? During lunch today, I saw him look back at her. Positive. So, I'm guessing he likes her and he texts the whole period. Also, I've heard him talk before and I love his voice. I also was riding with my mother in the car to go to school and she told me later I was smiling for ten minutes straight. I know I was thinking of him but its so embarring! This is unhealthy. How do I not like him? I'm very infatuated with him. Right now, I'm on x-mas break. I've never had a boyfriend, I don't know the signs. I also have high hopes, because during lunch sometimes, in the corner of my eye I can see him looking over at my table. Maybe its not my table or maybe he thinks I'm some obnoxious nut laughing so hard that I may spit out a watermelon! But, when he never looks over, I think to myself, "Look at me, dang it!" I know. I know. It's really sad. But, whatever. I also hate to admit it but I tried to find him on facebook.. But no luck. I'm not a stalker, for real. I don't know what cles he has, I don't know where he goes during school, I don't know how he goes home, I don't even know his friggin' name! That's so not stalker. So, help a girl out. Help me get over him. And no, I'm not walking up to him and say "Hey, how's it going? I noticed your wearing pants!" Then saying something really dumb and then he proceeds to call me an oaf.. I prefer to not get public humiliation from my crush. Thank you very much. Is there some way I can get him to notice me? I know I've asked this question before but, a girls got to do what a girls got to do. And that doesn't mean what you think it does. It means talk to him without anything coming out of my mouth/approaching him.
