What Breaks When A Heart Is Broken? Poem by robert fort

What breaks when a heart is broken?
Certainly not the flesh:
the muscle pumps along
oblivious to the pain
the brain is explaining.
Not the rhythm of the days -
even when the voice has lost
the will to sing along.
The empty house stands silent
but for an echo of laughter
and the lost groans of passion
inside a cold, conflicted head.
It's not the crackling nerves
pulsing and palpitating
at the top of awareness.
What's broken are the oaths:
the sincere I love you's,
the gratitude that destiny
sent this love your way,
the promise always implicit
in every kiss and coo.
No, it's the spirit that shatters:
the faithful soul that means no harm
the essence betrayed by reality
when the word goodbye rushes out
and the end you never want
comes too soon.
