Guys!? what does this mean when....?

well there is this guy at school his name is kris and i like him a LOT! he is like sooo funny and nice a sweet but it kinda seems like he is afraid of me..... like cuz i was walking to volleyball practice after school and he was talking to his friend and he just stared at me and walked to the other side of his friend (so i couldn't see him)..... does he have some problem with me or is he just acting weird cuz he likes me or something?
