I'm freaking depressed. should this be bothering me so much?

okayy so I like this guy alottt. the problem is, he's a sophmore & I'm in seventh grade. but I'm very mature for my age and he talks to me all the time. he's soo sweet and nice. I'm not a slut at alll. but he seemed perfect. he tol me how shy he was around girls and how he's not a player at all. he thinks of us as best friends but I want him to like me. please don't tell me he's too old. I know. but last night. asked him if he was even a virgin and he said this " haha that's for me to know and you to not find out for a while" ?. then I said " your not?!" and he said "I'm not tellin yah ;]" sooo I'm thinkig he isnt because he would deny it if he wasn't. ever since then, when I think of him (which is all the time). get this weird feeling. I don't know what it is. we go to a catholic school but he's in the high school. is it nothing out of the ordinary for a sophmore guy not to be a virgin? why is it bothering me so much? please just help me. :"(
