I NEED to tell someone how I feel, help?

[justagirl]

So I like this guy, we're both 15. He's not the best looking guy in school (I'm not the best looking girl) but for some reason I just feel happy around him. We speak a lot on Facebook but I haven't really been friends with him long enough to ask him out or anything. He's really shy in real life, when we're on our own he never says anything really but when our friend groups mix he's really talkative. I don't know why I like him, I just do. Sometimes I feel a bit awkward talking about boys to my friends (they don't know) because he's always on my mind. I never message him on Facebook, but if he comments on my status then I'll always reply. I check if he's online a lot too. Am I normal for feeling like this? I feel really stupid right now...
