By definition, you can have at most one best friend. The term best means better than any other. You can have lots of good friends, however. Stop calling your friends best friends, and call them good friends. Then they don't have to compete with each other to find out who is really the best friend.
Tell your friend. She will find out one way or another
You don't tell him. Just go with the flow, and let you best friend tell him.
its not really a best friend to be honest, if she don't tell you about her crush but she tells another person, than more and likely she is more closer to that other person than you, there is no trust in that friendship so its not a friendship because best friends should tell everything to them and be honest as well all the time.
Ask another close friend if they know if he loves you back.
You can just go out an tell her: "Hey i need to tell you something or let's have a talk. I know you've been my friend , But im starting to like you." Or you could get another friend to tell her.
tell your best friend but tell her not to tell her bro.
ask a friend to tell him
ask a friend to tell him
you should propably tell you best friend that is a girl she can help.
Tell her, shes your friend!!
Ask her. If she is really your best friend she would have told you and if she is your friend she'll tell you when you ask her.
Well you can tell your best friend to tell your best friend to tell him or you can be brave and go up to him and say i dont know how 2 tell u this but i like u. i'd go with the friend 1.
