alright well just to let you all know this isnt the whole song, its just the chorus. 

If you believed
C5      F5           A5             G5
when i said, Id be better off without you
         F5            A5          G5
Then you never really knew me at all

If you believed 
C5      F5
when i said
       A5                    G5
that I wouldnt be thinking about you
    F5                    A5               G5             D5            
you thought you knew the truth but you're wrong, you're all that i need
     E5
just tell me that you still believe
