Boy Probs

I need help! i have a number 1 crush on this ferociously cute guy named andrew but so does my best freind and i`d do anything to please her but shes had so many boyfreinds! i had ONE-10 years ago-and we wern`t even together for a year because he moved. How can i tell her i want andrew to be mine? he said hi to me but i think he might like my freind better. I`d be heartbroken if he does. What do i do?
