The tale of the lost bit

A little bit of my heart broke off today.
I know just where I lost it...
but I think I'll let it stay.
The crease that turned to a gap
began a while back.
I felt the soft organ bend and twist
like the snapping of someones wrist
The brake came slow with pressure ever increasing
But then it was only a small piercing.
It throbbed
but the piece stayed lodged.
But today that fault finally cracked completely.
A few salt tears traced the line quick and sweetly.
The little bit fell
As I hugged him well,
"We'll see him soon," I whispered to the little bit
It nodded, but disappeared into his pocket.
"Pathetic," I muttered
"You said it," it shuddered.
But I let it go anyway...
