Verse:
Am                          C             G              D
 Hey girl, is he everything you wanted in a man? 
                  Am                               
You know I gave you the world 
C                              G        D
You had me in the palm of your hand 
                 Am                            
So why your love went away 
C                           G         D
I just can't seem to understand
                    Am
Thought it was me and you babe 
C                      G
Me and you until at the end 
                    D
But I guess I was wrong 

Pre Corus;
Am
Don't want to think about it 
C
Don't want to talk about it 
G
I'm just so sick about it 
D                                                       Am
Can't believe it's ending this way 

Just so confused about it  
C
Feeling the blues about it
G 
I just can't do without ya 
D                         Am
Tell me is this fair?
Corus: 
                     C              G
Is this the way it's really going 
    D            Am
Is this how we say goodbye?
 C                                       G                     
Should've known better when you came around 
    D                              Am
That you were gonna make me cry 
C                                          G                  
It's breaking my heart to watch you run around  
D                                      Am
'Cause I know that you're living a lie 
C                                 G                   D
That's okay baby 'cause in time you will find...

Repeat....Same Thing

Now girl, I remember everything that you claimed 
You said that you were moving on now 
And maybe I should do the same 
Funny thing about that is 
I was ready to give you my name 
Thought it was me and you, babe 
And now, it's all just a shame 
And I guess I was wrong 

Repeat Pre corus And Corus
Am                        C                    D
What goes around comes around.
 Am                             C
What goes around comes around 
G                               D
You shouldn't know that 
What goes around comes around 
You shouldn't know that 
Repeat Pre corus and Corus
 
Am
You spend your nights alone 
C
And he never comes home 
G
And every time you call him 
D
All you get's a busy tone 
Am 
I heard you found out 
C
That he's doing to you 
G
What you did to me 
D
Ain't that the way it goes 
Same thing:

You cheated girl 
My heart bleeds girl 
So it goes without saying that you left me feeling hurt 
Just a classic case 
A scenario 
Tale as old as time 
Girl you got what you deserved 

D      Am           C       G
And now you want somebody 
To cure the lonely nights 
You wish you had somebody 
That could come and make it right 

D            Am               
(What goes around comes back around) 
I thought I told ya, hey 
(What goes around comes back around) 
I thought I told ya, hey 
(What goes around comes back around) 
I thought I told ya, hey 
(What goes around comes back around) 
I thought I told ya, hey 

End in        D        Am         C                       G
