My first tab! I'm not sure if this is absolutely 100% correct since the song just came 
and I heard a rough recording but it's gotta be pretty close. I wrote this for people to 
an idea of the chords used. Experiment...

            Dm            G7          C
You've been talking 'bout leaving for 2 weeks
    A7            Dm             G7          C
and counting well can't you just makeup your mind
A7       Dm              G7      C
I like a girl who is true to her word but more
A7          Dm          G7
than that a girl who is true to her heart
   C
So if you go if you go let me know
                      Am
let me know that your gone
        A7        F
and your not coming back
Gm7              C
cause i wouldn't have that
G7    Dm         G7           C         A7
So the hours were creeping and you keep repeating
 Dm       G7           C
you never have felt so alone
    A7     Dm            G7
but babe i told you last week that
   C            A7          Dm
my heart was to keep if you told
        G7
me that you would stay home


 C
So if you go if you go let me know
                      Am
let me know that your gone
        A7        F
and your not coming back
Gm7              C
cause i wouldn't have that
    C                                     Am
and if you stay if you stay tell me right away
    A7       F      Gm7
ill give you one last chance
           C
to pull my heart strings
G7   Dm
Baby all i ever wanted for you was the
           G7                C
best but i guess your second guess
                         F
was your best bet to get out of this town
       Fm                  Dm
but it brought you farther down down down
                        G7
just like i was with my heart on a thread and
   C                      F                 C
my soul on a run well ill give you one last chance

Harmonica part:

Dm, G7, C, A7

so if you go if you go let me know let
me know that your gone
and your not coming back
so i can have my heart back
