I'm Not The Only One

Sam Smith / James Napier

You and me, we made a vow
For better or for worse
I can't believe you let me down
But the proof is in the way, it hurts

For months on end I've had my doubts
Denying every tear
I wish this would be over now
But I know that I still need you here

You say I'm crazy
'Cause you don't think
I know what you've done
But when you call me baby
I know I'm not the only one

You've been so unavailable
Now, sadly, I know why
Your heart is unobtainable
Even though, lord knows, you have mine

You say I'm crazy
'Cause you don't think
I know what you've done
But when you call me baby
I know I'm not the only one

I have loved you for many years
Maybe I am just not enough
You've made me realize my deepest fear
By lying and tearing us up

You say I'm crazy
'Cause you don't think
I know what you've done
But when you call me baby
I know I'm not the only one

I know I'm not the only one
I know I'm not the only one

And I know, and I know, and I know
And I know, and I know, and I know

I know I'm not the only one
