Do I like him or not? I'm so confused...?

Okay, so there's this guy. I've only known him for about six months or so, but I'm starting to feel like I might have some more-than-friendly feelings for him. But the thing is, I don't know if I actually have feelings for him or if I just WANT to have a crush on somebody. I mean, it feels real most of the time, but sometimes when I'm not with him I wonder, "Why would I like him?" He's not mean or bad or anything, don't get me wrong. It's just that his personality can be a little boring sometimes and he's very quiet (which isn't always good, because I'm quiet too). He's so sweet and cute though! Today at school one other guy asked him if we were going out because I was subtly flirting with him, and I didn't hear the way he answered. But like some infatuated eleven-year-old, just the thought of going out with him made my heart pound and my lungs tighten. I don't know! Can someone help me make up my mind? I'm so confused...
