Try being your self. Maybe do some things he is interested in doing. Like if he likes doing a certain sport try doing it to. Just don't act all snobey. Be nice and just treat him like everyone elese until he starts showing interest in you and don't be to clingy.
Im not very good at talking to guys even though all of my best friends r guys...but i really really really like this guy. How can get him to notice me?
Try wearing your trendiest and coolest outfit and just start talking to him about ordinary stuff like music, movies or even fashion or sports.It doesn't matter really - anything to get a conversation going to get to know him better.
