What do you do if you are a 12 yr old girl ur bf wants to break up w someone u like one of ur friends that friend likes someone else u have never gone out and ur bf now likes the person u like?

Sorry about the grammar, there wasn't enough room. "What do you do if you are a 12 year old girl, your best friend wants to break up with someone, you like one of your friends, that friend likes someone else, you have never gone out with anyone, and your best friend now likes the person you like which is also her friend?" also, I don't really want to go out with him, it's just that I don't want her to go out with him, and I don't want to hurt my friend's feelings. And, she still wants to be friends with the person she wants to break up with. (it's a group) The person she is trying to break up with is the person who I like's (and my) friend. Help!
