Sam Smith - I'm Not The Only One

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 kept mine
