[Intro]
E Asus2
E Asus2

[Verse]
E                                                      Asus2
Long were the nights when my days once revolved around you
E                                                   Asus2
Counting my footsteps, prayin' the floor won't fall through, again
B                       C#m       B
My mother accused me of losing my mind
      Asus2
But I swore I was fine
E                                                  Asus2
You paint me a blue sky and go back and turn it to rain
      E                                                        Asus2
And I lived in your chess game but you changed the rules every day
B                          C#m         B          Asus2
Wonderin' which version of you I might get on the phone, tonight.
       B                           C#m        B            Asus2
Well I stopped pickin' up and this song is to let you know why

[Chorus]
     E                                  A
Dear John, I see it all now that you're gone.
                          C#m
Don't you think I was too young to be messed with?
    B                           A
The girl in the dress cried the whole way home.
          E      Asus2
I shoulda known.

[Verse]
     E                                      Asus2
Well maybe it's me and my blind optimism to blame.
           E                                                Asus2
Maybe it's you and your sick need to give love then take it away.
    B                          C#m          B
And you'll add my name to your long list of traitors
    Asus2
Who don't understand.
              B                    C#m               B
And I'll look back in regret how I ignored when they said
        Asus2
"Run as fast as you can."

[Chorus]
     E                                  A
Dear John, I see it all now that you're gone.
                          C#m
Don't you think I was too young to be messed with?
    B                           A
The girl in the dress cried the whole way home.

     E                             A
Dear John, I see it all now it was wrong.
                               C#m                        B
Don't you think nineteen's too young to be played by your dark twisted games 
       A
When I loved you so?
          E     Asus2
I shoulda known.

[Bridge]
           C#m
You are an expert at sorry
    B
And keeping lines blurry
    A
And never impressed by me acing your tests
        C#m
All the girls that you run dry
     B
Have tired lifeless eyes
           A
'Cause you burned them out
    B
But I took your matches
  C#m             B
Before fire could catch me
   Asus2
So don't look now
    B
I'm shining like fireworks
A                   E     Asus2    C#m    B    A
Over your sad empty town

[Chorus]
     E                                  A
Dear John, I see it all now that you're gone.
                          C#m
Don't you think I was too young to be messed with?
    B                           A
The girl in the dress cried the whole way home.       
E                                A
    I see it all now that you're gone.
                          C#m
Don't you think I was too young to be messed with?
    B                       Asus2   
The girl in the dress wrote you a song.

[Outro]
            E    
You shoulda known.
            Asus2
You shoulda known.
E                              Asus2
     Don't you think I was too young?
                   E
You shoulda known.
