She was free
His heart sank.
It happened while she was watching. She supposed it had always been coming; in fact, she knew it had been. It was all he’d had to give. For months; ever since it had happened. They’d gone through so much together; then the accident, but he’d held on.
“My heart will always be yours,” he’d said, “until the day it sinks so completely and can never rise again. When it does, you’ll be free”.
Six months had passed since he died.
She stared at the heart at the bottom of the jar of formaldehyde.
She was free.
My Words, My World 
The more I read it, the more I like it. My mind is conjuring magnificent images.
Good morning Lorraine.
Thank you for that. I had the phrase “his heart sank” swimming around in my head for a while, but didn’t know what to do with it. Then I went to the pub for a swift one, and while the world around me sat glued to their cell-phone, I took out my notebook.
