A piece in your game

How will I ever
Move on from this pain
You’ve left me alone
A mere piece of your game

I knew you were a player
But I thought it’d be different
I thought you were
The kind of guy who listened

But oh how I was wrong
And guilt floods my soul
Regret fills my heart
But only you can make me whole

My world is upside down
I’m so confused
You left me blank
And I don’t know what to do
