 [Verse 1]

     C#               Ab          F#
 You only know what I want you to, 
         C#                   Ab       F#
 I know everything you don't want me to.
         C#                     Ab        F#
 Oh your mouth is poison, your mouth is wine...
        C#                         Ab       F#
 Oh you think your dreams are the same as mine...

 [Chorus]

    C#                       Ab 
 oh I don't love you, but I always will, 
    F#                              
 oh I don't love you, but I always will.
 C#                       Ab
 I don't love you, but I always will, 
   F#
 I always, will..

 
thats pretty much all, just play the same thing for the other verse and rest of the song.
