One Question

My heart aches,
With the pain of the past,
No matter what I do,
It will always last.

Memories haunt me,
They'll never leave,
No matter how hard I try to relax,
I still can't seem to breathe.

You took my heart,
And tore it in two,
I try to forget,
But my thoughts always lead back to you.

I'm finally moving on,
But theres just one question to ask,
How could you do that to me?
You must be heartless.
