I came here as a friend 
Though I don't really know you 
I know you're in love with him 
And he's made your world brand new 
I know you think he loves you 
And he may believe it too 
Pour some coffee and I'll tell you 
What you'll soon be going through 

(Chorus:)
When he leaves you 
It's gonna more than break your heart 
When he leaves you 
It's gonna tear your world apart 
And you're gonna cry a million teardrops 
One for every shattered dream 
When he leaves you 
And come back home to me 
I've known him all these years 
Honey this time's not the first time 
I've paid for loving him with tears 
And when it's over he'll be mine 
I can see that I've upset you 
Guess I'm a fool to try and to help 
When it comes to hearts and heartache 
You go to find out for yourself 

(Repeat chorus) 

When he leaves you 
And comes back to me
