I have a crush on this guy

Quick facts:

-like him for almost a year

-was his classmate for 3 years

-we're friend but not close enough

-my friends suspected that he likes me before but he's confusing

Okay,I'm gonna address him as A. I'm not sure wether A knows that I like him or not. Sure, my friends always tease me when he's around but I'm not really sure wether he notice it or not. Not being delusional but me and my friends thought that he likes me because he's sending many signal. Mind me but it's actually mixed signal. One time, he acts like he's interested in me. And at one time he makes me feel that I'm trapped in one sided love. He really makes me think that he likes me because he used to stared at me in our class. He also used to tease me and all. But lately it stops because our class change and I rarely interact with him. But I do saw him though. I *thought* that my feelings died but I guess not. Apparently, his friend (call him C) is my classmate for this year. He always tease me about A. I didn't know why. Out of the blue, he's calling me by A's full name. You know what, I feel shock and paranoid. What if he knows that I like him. I'll be embarrassing. (I forgot to mention that A and his friends are famous in my school. Anything related to them will spread all over the school) btw, A's other friends would mentioning his name when I'm around. Even if A is not around .This makes me really suspicious.I'm not sure wether he knows that I like him or does he likes me. Helllllppppp meeee!!!
