The original is performed in open D but play the following chords with capo on 2 and its close enough.

Intro:
I think the chord is called Am2 -  x02200

Verse:
      Em                        G       D       A
Mama why does he treat me so cold so cold so cold
Em                 G      D     A
Why do I feel so old so old so old
     Em                      G       D      A
how long has he treated me unkind unkind unkind
     Em                    G         D       A
or have I always been so blind so blind so blind


Chorus:
        Em              C               D       Em      D
I'm the widow, I'm the widow, I'm the widow of a living man
        Em   D          Em   D   C   A   Em2 --> see above
of a living man of a living man

For subsequent verses and choruses, repeat the above pattern.

Verse:
Why can't the times stay the same
now i am begging him to change
what about all the plans we've made
now i am so afraid

I'm the widow of a living man

Verse:
why does he hurt me so
I'm gonna need somplace to go
he's no longer some kind woman's son
mama i think that I had better run

Chorus:
I'm the widow of a living man
