My best friend and the girl I like are crushing on each other...advice please?!?!?

does your friend know you like the girl? i think you should talk to your friend and explain how you feel about the girl, if he doesn't already know. If he's a true friend he won't take it any further with this girl out of respect for you. If it turns out you both like the girl i think you need to decide if either of you will go for it with her, or if you're both going to step back.
