Answer:
Um.... Based on my experience in the 6th grade, guys are VERY immature and it is rare to come across one that will not break your heart. If it was me, I wouldn't care but now that you mention it... the best way is to pay attention to him. If he looks at you all the time but looks away when you look or he is always listening to your conversations, then these are all signs that he likes you. Since you dont know that for sure, when you think it is VERY possible, you are going to have to get up the courage to ask him and be honest.
