Help please!!

So there is this guy that I have had a crush on for the past few years. I've known him since I was in 4th grade and he was in 5th (I'm currently a junior in high school). We had classes together for the past three years. When he is sitting next to me in classes he talks to me or when we walk past each other in the hallways. He sometimes goes out of his way to talk to me. When I talk to him he seems like he actually cares what I have to say. There are no sighs that he is really trying to flirt with me. He just talks to me like I am one of his guy friends. I just don't know if he likes me the same way that I like him. What do y'all think?
