I have known this guy since I've been in middle school. Ever since then, I've had a crush on him. He's going off to college this year but recently we've been talking online and I'm getting to know him better. The other day we ran into each other and he smiled at me in this way that he used to do. I want to tell him that I like him but I don't see him that often. How should I tell him online without it becoming wierd between the two of us if he doesn't like me?
