Will She Come Back?

MET THIS GIRL AND WE BOTH HAD A FAST ONE THINKING IT WAS LOVE AND I BELIEVED HER.WE HAD A SIMPLE QUAREL WHICH I CAUSED AND SINCE THEN I HAVE BEEN ASKING HER TO COME BACK BUT SAYS A BIG "NO" THAT ITS OVER B/W US.
DO I TRY HARDER OR DO QUIT ASKING HER TO COME BACK,COS I AM IN LOVE WITH HER AND SHE KNOWS IT COS I LET HER KNOW,
