I'm playing this with capo on 3rd fret, but I think you have to try out what feels good.

G             C/B      Bm
I don't know what to say
G             C/B      Bm
I don't know what to say
G             C/B      Bm
I don't know what to say
G             C/B      Bm
I don't know what (to say),

              C/B       Bm              D7
I could say I want you that would be a bore
            C/B        Bm              Dsus2
Maybe in a font you've haven't seen before
                 C/B        Bm               D7
I could say I'll haunt you 'till your dying day,
                  C/B        Bm               Dsus2
I could tease and taunt you, but what would I say?


It's the same chords through the whole song!
