Does he like me? PLEASE ANSWER! I NEED HELP!!?

Ok, well there is this boy I REALLY like. You have no idea how much I like him. Well, I want to know if he likes me. It seems like he looks at me a lot like I do to him. He is near my homeroom(I'm in highschool), and we always seem to look at eachother when he goes up the stairs to go to his homeroom. But then, we look away quicky. And one time, he went past me and we looked at eachothers eyes for about 3 seconds or more. Maybe 2, I don't know. It did seem long. And also, one time I saw him so I decided to go his way when I was going home, so I went past him and he was near me and I could feel him looking at me, so i looked and he quickly looked away cause i caught him looking at me. Also, when he was walking with his friend today, his friend looked at me then my crush looked at me..and then his friend said something to him..and i dont know if it was about me. I really need help!! Also, since he is near my homeroom, I knew he was behind me waiting to go in his clroom, so i looked at he was looking at me... does he like me? I did compliment him once.. Oh, and one more thing, one time i was walking up stairs and he was downstairs(i didn't know that he was downstairs at that moment) and I was looking at his friend(who was also down stairs) because you know, he knows my crush alot. so i looked at his friend again and turned my back looking downstairs and he was looking at me but then quicky looked away. I mean, he was looking at me when I was upstairs and he was downstairs?? PLEASE HELP AS SOON AS POSSIBLE!!
