why this should happen again?

it's sad when know he likes someone else, who had also never take a guy who I like even now he was hers, but why should it now? I do not want this to happen. Oh God help me, what should I do?

he never said if he can not love with another girl but why is he now likes the other girl? I hope it will not happen. and I hope it happens to me. why are destiny requires walking like this when I was close and friendly with the guy but why are there new problems?
