My brothers best friend is my crush!?

Kinda of same sitautiOn happened to me but if u were the other way around and u were trying to keep ur best friend from ur sid how would u get a way with it. U cant. The thing is u got to talk to your bro cause from the sound of it he is going to far with things. And all u have to do is talk to him and tell him that u just wanna be friends and if that works u guys can talk and maybe go to the next step
