A Perfectly Good Heart Chords

This is my first tab, so it might not be very good. ^^; I think it's really close, though.

Taylor Swift - A Perfectly Good Heart

CHORUS:
D                             A
Why would you want to break a perfectly good heart
Cadd9                          Em7
Why would you want to take our love and tear it all apart now
D                              A
Why would you want to make the very first scar
Cadd9                     Em7                  D
Why would you want to break a perfectly good heart

VERSE:
Em7    Cadd9               D
Maybe I should’ve seen the signs
                   A
Should’ve read the writing on the wall
Em7        Cadd9                        D
And realized by the distance in your eyes
             A
That I would be the one to fall
Em7                Cadd9
No matter what you say
                 Em7
I still can’t believe
                     Cadd9
That you would walk away
              A
It don’t make sense to me but

REPEAT CHORUS
Em7        Cadd9        Em7
It’s not unbroken anymore
         Cadd9                        D    A Cadd9 A D A Cadd9 A
How do I get it back the way it was before?
