Unbreakable Heart

SImple poem I wrote...

A heart does not start unbreakable,
One creates an unbreakable heart
Who my darling created yours,
So all I feel is cold and hard.

Attempts to cover this heart are futile
There is never a way to mask it
There is no love within you,
Only hate in the cold hard heart.

You can play it off as being hurt
But everyone knows the truth,
There is fear in your cold hard heart,
The fear of letting someone in.
