LOVE PENTAGON... HELP!!?

My brother is madly in love with his good friend, and his best friend, is in love with her to... but she's dating my best friend who i might be in love with... he's only staying with her because he's on the football team and her dad's the coach.. Shes totally in love with my best friend but he told me a few weeks ago at our graduation party that he wanted me :(... Now I dont want to hurt her but she already has two guys fighting over her, and it totaly ruining my brother and his friends relationship, and I want to be happy and so does my best friend with me... but if he chooses me over her then what happens to position in football? Im SO confused. I resently found out that my brother's best friend didnt come to his graduation party because of this situation... its getting way out of hand and i'm scared for everyone involved feelings. For my birthday, my best friend gave me a friendship braclet and his girlfriend became angry- not at him but at me... so now because shes mad at me she doesnt want to see me anymore thus shes not seeing my brother... which is making this way to complicated... Im only a sophmore.
