Please don't be in love with someone else..

Today was the last day.. I'm officially out for the summer.
Honestly I'm not sure what I think about this. I'm excited that schools over, yet I'm kind of disappointed. I know, most people would be like what the crap, she's crazy! But well, there's this guy...
Don't all interesting stories start with "Well, there's this guy? (:
We just started getting close the past few weeks and well, there's feelings... shocker. Who didn't see that one coming?! Honestly I never thought I would have feelings for him, but then I got to know him and now I can't seem to get him off my mind. There's one problem, he has a girlfriend. Um yeah... fml. (I HATE that saying, but it applies)
People always say, if he messes with you when he has a girl, then he'll mess with someone else when you're with him. Heck, I say that! But I just half care yet half don't. I'm being careful, yet how can you be careful with a guy like him!? All I know is I haven't felt like this in a while, and I like it..I like him.
He makes me smile, he makes me laugh, he makes my day, he cheers me up, he calms my mood.. I could go on forever! He texts me and I blush for like five minutes. Is this abnormal? I'm just honestly kind of scared, some people might say "why are you even scared, you're just a ho!" But I'm scared because I don't want to just be that " back up" if him and his girlfriend don't work out. I want someone who falls in love with me because of me, not because he's bored. I don't want to be his "in case" girl...I'm just scared of being hurt.
Maybe I'm reading into this too much, maybe he doesn't like me like I think he does..
Maybe..

I don't know what I am to you. And I don't know what I mean to you..All I know is every time I think of you, I want to be with you..
