[Verse 1]
You called me out and it was all for nothing
Now everything is set in stone
I can never look at you the same way
What have you done to the friend I used to know?
You helped me out when I needed you most
Stuck it out since the day I met you
I took your side over everybody else
Never mattered if you were in the wrong

[Pre-Chorus]
You must've had a sudden change of heart
Because you think that you know, wе both know you won't
Because I know you bettеr than you think

[Chorus]
Here we go and tell me
How do you sleep at night just knowing you left me down?
(You left me down)
Do you lie awake, no probably not
You never really had it in you
(Tell me)
How do you sleep at night just knowing you left me down?
(Yeah you left me, yeah you left me)
Do you lie awake, no probably not
You never really had it in you
[Verse 2]
Take me back to the very summer
I noticed a change in your approach
And you know that I know that you tried
But I don't think you put your best foot foward
How did three months ruin a lifetime?
On the spot you were my lifeline
Hold your tongue, think before you speak
Before everybody got to know you
There was you and me trying to make things better
Maybe it's much easier said than done

[Pre-Chorus]
You must have had a sudden change of heart
Because you think that you know we both you won't
Because I know you better than you think

[Chorus]
Here we go and tell me
How do you sleep at night just knowing you left me down?
(You left me down)
Do you lie awake, no probably not
You never really had it in you
(Tell me)
How do you sleep at night just knowing you left me down?
(Yeah you left me, yeah you left me)
Do you lie awake, no probably not
You never really had it in you
[Refrain]
I don't know you
Anymore
I don't need you
It was you who changed
I don't know you
Anymore
I don't need you
It you who changed
