I keep liken the same boy ! read more ..?

ive spoke to him a few times and hang out with him but it was because my friends were hanging out with his friends it felt like i was in a world of my own and when people laughed hat night i would laugh like i was listening but i was just doing that i really like him and no-one knows well i don't think because a while ago i never knew him and a was like a pure stalker and he didn't like me im ok with him now but he doesn't fancy me i dint want to fancy anyone how can i stop feeling this way ( the first time i fancied him he knew this time he doesn't !!)
