Ok so I was hoping that maybe my fellow witty members could help me with my guy situation. It's a really long complicated story but I will sum it up. 

I have liked this guy in my school for 3 years now (well 3 years in October) and I don't know if he likes me back. We used to be friendly and now we are just aquatiances since we went a year without classes together. He shows many signs that he may like me and all my friends think it is possible (like the fact that he stared at me the whole english period yesterday) although many things that have happened between us previously make me think that he does not like me. I have a very big fear of rejection so I am nervous that if I tell him I like him he will not feel the same way. I have given him many signs that I like him and I smile at him all the time, I have not talked to him in a while though. I really really like him and he is all I ever think about and because of him I can't like anyone else for some reason my heart won't let me. My heart keeps telling me its meant to be but I really don't think he feels the same way I do.

WHAT DO YOU THINK I SHOULD DO?!?!? Many of my friends tell me to give it time and if its meant to be it will happen but I can't just do that because I have wasted enough time if it isn't going anywhere. Please help me decide what to do...is it better to not say anything or to tell him and risk heartbreak?
Sorry its long but please read it and help me, I would be sooo appreciative.
