Love Poem: Game of Card

Game of Card

You played me like a card
Everytime you're about to loose
You'd pull me out 
When you win you'd set me aside...
You'd say I'm a queen of hearts
Your favorite out of the deck
I should of known better 
You called her the same too
Last I checked there's only one queen of hearts...
And that ain't me.....
I rule in a castle.
