CONFUSED????

ONE OF MY CLOSE FRIENDS BUT NOT SO CLOSE HAS JUST TOLD ME SHE WAS BI. I WAS IN SHOCK WHEN SHE TOLD ME. NOT ONLY DID SHE JUST COME OUT SHE WAS GOING OUT WITH MY BEST FRIEND, THAT IS A GIRL. SO NOT ONLY DID ONE FRIEND COME OUT BUT TWO DID. I AM WAY CONFUSED!!!!! I THINK THEY ARE BOTH GOING THROUGH A FADE. I HOPE NOTHING REALLY GOES ON BECAUSE AFTER THEY BREAK UP THE BOTH ARE GOING TO REGRET IT.
