Does he like me more than a friend?

Well, there's this guy who was in my chemistry class and we just finished up school a couple of weeks ago. I've known him for a little more than two years and I think of him as a nice guy. A lot of people tell me that he seems to act like he likes me, but I guess I never really noticed until people began to mention it to me. Back when I first met him he was quiet and nice, and we began talking every class, and near the end of the year he grabbed my hand and held it in the hallways, so I didn't really know what to do or what to say. This year he was always helping me, he came into the class and sat with me, he always talks to me, and he always makes me laugh. I don't know, does he like me more than a friend? He hasn't told me so I dint know. What can i do to get him to tell me? Thanks in advance for the help.
