Well, there is this girl that I like, but I am afraid of telling her for fear of rejection, and I also think that this girl doesn't like me the way I like her.
Advice?

The only way is to just tell her how you feel... you may get rejected or you may not.. the worse thing that can happen is her telling you she don't feel the same way.. but you will never know if you don't talk to her. And you will always wonder "what if"... And if she does not like you in the same way, you two can remain friends, it just means she wasn't the one for you.
