Beautiful, simple song. 
He strums the low G every other strum on the C chords and the low E on every other Am strum
C/G
All the people that I once knew
                                Am
That built cities in my mind

On the mountains and rivers
                    G
That I've left behind

C
And there lives the villain
                    Am
Who sets me free

I'm waiting for you love
                   G
To come for me

C
And I hope I never see you again
Am                       Em
You've ruined my heart
C
I hope I never see you again
     Am                  G
You've ruined my heart

C
At least you don't write me
                Am
At least you don't call

At least you don't lend me
        G
Any hope at all

C
At least you don't miss me
                    Am
Or at least you don't give
At least you seem distant
            G
Wherever you live

C
And I hope I never see you again
Am                       Em
You've ruined my heart
C
I hope I never see you again
     Am                  G
You've ruined my heart

        F
Ruined my heart

              C         G         F
And of all the ways that it could be
                   G              C¬
I wish you'd fallen in love with me

C
Well I work in the morning
                     Am
I work at the same

Fixin' these melodies
                 G
To fit your name

C
Some years I will travel
                           Am
Some years I will not

Maybe life will unravel
                                   G
And leave me a second shot

C
And I hope I never see you again
Am                       Em
You've ruined my heart
C
I hope I never see you again
     Am                  G
You've ruined my heart

        F
Ruined my heart

              C         G         F
And of all the ways that it could be
                   G              C
I wish you'd fallen in love with me

Am       F                        G              C
       I wish you'd fallen in love with me
