A sad love poem

Prompt: Write a love story. The story must end badly
Me: *cracks knuckles* I eat tragedy for breakfast...

She and he became they
Eternal love they swore 'til death
Poisoned by a vile tongue
Apart, they begin to grow.
Rare now, is love between them
Another, he starts to see
Together, a word she starts to hate
Ending, both grow cold
Dying, both alone.
