What Happened?

I was in the top
Nothing could bring me down
I thought my life was fine
Until it all turned around

You lied
You cheated
You killed my heart
You teared it apart

There were too many things between us
Things that both couldn't pass by
And that made our love collide

It just teared apart
Without and answer to my question "Why?"
Why I feel live I've died
But you didn't answered
You just kissed me good-bye

Since that moment I was never the same
Everybody noticed I changed
But nobody cares
or...it someone there?
