Dying inside

Days were so good
Having you by my side
But then we broke up
And it killed me inside.

Two years have passed
And I met this guy
Who I feel the same way about
And I never want to say goodbye.

He makes me so happy
Just like you used to do
I'm so glad I met him
My days are no longer blue.

But now you have come back
Trying to mess with my head
But I'd never leave him for you
I'm sorry, I'd choose him instead.

So just back off
And stop messing with me
I'm giving him my heart now
And only he holds the keys.

So leave me alone
Stop with your lies
I don't want to hear it
Because it kills me inside!
