Should I give up liking this girl I have a crush on?

I’m in 6th grade and my best friend used to be treated badly and called a nerd. I stood up for him, and told him his day to be praised would come. On the talent show, he sang amazingly (while I sucked the life out of my peers with stupid magic tricks) and everyone treated him with respect and like a popular kid. The girl I have a crush on, who I can’t talk to and who I admire for being not being as flirty as others started liking my best friend, and asked him out. Now I want to know if I should stop liking her for my friend.
