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

If you believed
C      F           Am             G
when i said, Id be better off without you
         F            Am          G
Then you never really knew me at all

If you believed 
C      F
when i said
       Am                    G
that I wouldnt be thinking about you
    F                    Am               G             Dm            
you thought you knew the truth but you're wrong, you're all that i need
     E
just tell me that you still believe
