(intro) Em Am

(Em Am)
I don't know where to begin 
Fighting a war I can't win  fighting a memory
Something that used to be  (Mmm)
No matter how hard I fight 
All of my strength and might 
Keeps on defeating me  it just keeps on defeating me.
(Em Am)
So what I'm trying to say  I know what's happening 
Your body is here with me 
But your heart and your mind is still with him.
(Em Am)
Go back to what you know 
Go back to where you know where your heart is 
Girl  just be honest  this is impossible 
This is impossible  we'll never work cause you don't
want it 
Girl  you belong with him so just go back to what you
know 
Go back to what you know  because this is impossible.
(Em Am)
Telling me things that you two  did when he was with
you 
How he was oh so sweet  the way that he used to treat
you 
Instead you just can't keep him outta your mind.
Why can't you just tell me that I'm not who you want
to be 
Baby you don't want me  no  no  no.
(Em Am)
So what I'm trying to say  I know what's happening 
Your body is here with me 
But your heart and your mind is still with him.
Go back to what you know 
Go back to where you know where your heart is 
Girl  just be honest  this is impossible 
This is impossible  we'll never work cause you don't
want it 
Girl  you belong with him so just go back to what you
know 
Go back to what you know  because this is impossible.
(Em Am)
And if that was really what you want 
I will not stand in your way  you want to be free
I will let you be 
I rather you have me  than miserable with me 
Back to what you know 
Back to what you know 
Said back to what you know.
(Em Am)
Go back to what you know 
Go back to where you know where your heart is 
Girl  just be honest  this is impossible 
This is impossible  we'll never work cause you don't
want 
Girl  you belong to him so just go back to what you
know 
Go back to what you know  because this is impossible.
So there ain't no need to make those lies
You're stuck in the past 
Pedal to the gas and drive away
