I HAVE A CRISIS

I WANT MY BEST FRIEND TO BE IN MY QUINCEANERA. MY COUSIN IS IN LOVE WITH HER.HE WANTS ME TO PUT THEM TOGETHER AS A COUPLE. I TOLD HER I WOULD HAVE HER BOYFRIEND BE HER PARTNER. IF I PUT MY BEST FRIEND AND MY COUSIN TOGETHER SHE`LL BE MAD AT ME. BUT IF I DON`T PUT THEM TOGETHER HE`LL BE MAD AT ME. I`M GOING CRAZY. DOES MY MOM HAVE THE RIGHT TO TELL ME WHO MY CHAMBELANE IS? SHE WANT`S MY BROTHER TO BE MY CHAMBELANE. I WANT THE GUY I`M TOTALLY IN LOVE WITH. THE ONLY PROBLEM IS THE BOY I LOVE LIVES 300 AND SOMETHING MILES AWAY FROM ME. HE TOLD ME HE WOULD COME DOWN FOR MY QUINCEANERA. WHAT SHOULD I DO? WHAT SHOULD I DO?
