What happned??

I don't know how you could
I thought that we would
we were supposed to stay strong
even if we knew we were wrong
i don't know what happen

I thought you loved me
but now I really see
that you were just pretending
that's why we came to our ending
tell me what happen

I really need to know
why did you put on a show?
were you hiding something else?
why did you turn out false?
now I know what happen
