There's this guy i like. I dont know if he likes me back or not. We dont talk much but whenever we do its always him starting the conversation and when talking to others he sometimes brings my name into it one way or another and says my name when someone else is talking about me. Sometimes i see him looking at me. Sometimes he looks away when i look at him and other times he keeps looking even if our family is around. Every now and then he smiles at me sometimes for no reason. He's in a relationship so i dont know what is he trying to do. Or what should i do?
