Lyrics:

[Verse 1]
I don't know where to begin
Fighting a war I cant win
Fighting a memory
Something that used to be

No matter how hard I fight
All of my strength and my might
Keeps defeating me
It just keeps defeating me

[Bridge]
So what Im tryin to say
I know whats happening
Your body's here with me
But your heart and your mind is still with him

[Chorus]
Go back to what you know
Go back to where you know your heart is
Girl, just be honest (this is impossible)
This is impossible
We'll never work if you don't want it
Girl, you belong with him, so go back to what you know

[Verse 2]
Telling me things you used to
Do when he was with you
How he was o' so sweet
The way that he used to treat you
And since you just cant
Keep him out of your mind
Science told me that I'm
Wherever you want to be
baby you don't want me

[Bridge]
So what Im tryin to say
I know whats happening
Your body's here with me
But your heart and your mind is still with him

[Chorus]
Go back to what you know
Go back to where you know your heart is
Girl, just be honest (this is impossible)
This is impossible
We'll never work if you don't want it
Girl, you belong with him, so go back to what you know

[Verse 3]
And if that's really what you want
I will not stand in your way
You wanna be free
I will let you be
I'd rather you happy
Then miserable with me
Back to what you know

[Chorus]
Go back to what you know
Go back to where you know your heart is
Girl, just be honest (this is impossible)
This is impossible
We'll never work if you don't want it
Girl, you belong with him, so go back to what you know
