This is worse than cheating.

 
Every now and then it hits her.. that he's the one that got away.
She'd spent years spitting venom to spite him,
to only poison what was left of her twisted heart.
And him; immune to it's mayem.

Blame blame... the victim game.

Convinced he could never change; she ran.
Ran as far as two suitcases and a 747 could take her.
Certain he'd follow her to the depths of hell,
But he instead became a ghost.

Not all demons... stay the same.
