What went wrong?

What went wrong?
Things were going so strong,
I guess you changed your mind,
didn't care about how i felt
just thought of your self

well thanks for the heartache
and all of this pain
you could of told me so much sooner
and saved this torment of mine

why'd ya have to go and do that?
build up my hope
and drop it down so fast
all the build up .. never to last

well this is the end
no more trying, crying
just nothing left
all emotions i had for you are dying.
