Just promise me

I have had enough of all this pain
i just want to end it
but u wont let me will you?
you wont so why must i ask?
i know u love me
but it's hard for me to stay here
my heart aches with this pain
i love u so
but we will never be together and i know it
i will try to stay
stay for you
just promise me you will never leave me
i can't make that promise to you
and i sorry for that

Just say you will love me forever
