Christina Perri - Jar Of Hearts Chords & Tabs

This is my first tab, I hope you all like it! It's very simple, so no need to shy away 
it, you beginners!
Being that I wrote these chords by ear, I wasn't sure about the Dm chords, it's the 
I could get to the song sounding well,
so if you have any better suggestions, comment!

CAPO 3

Am                             C
   I know I can't take one more step towards you
G                                Dm
   Cause all that's waiting is regret
Am                                 C
   And don't you know I'm not your ghost anymore
G                                Dm
   You lost the love I loved the most


Dm              C          G
   I learned to live half alive
Dm             C               G
   And now you want me one more time


C                           G
   And who do you think you are
                       Am
Running 'round leaving scars
                       F
Collecting your jar of hearts
                 C
And tearing love apart
                     G
You're gonna catch a cold
                         Am
From the ice inside your soul
                       F
So don't come back for me
                     C
Who do you think you are


Am                            C
   I hear you're asking all around
G                         Dm
   If I am anywhere to be found
Am                      C
   But I have grown too strong
G                            Dm
   To ever fall back in your arms


Dm              C          G
   I learned to live half alive
Dm             C                G
   And now you want me one more time

And it took so long just to feel alright
Am              E            Am          Dm
Remember how to put back the light in my eyes
  Am         E                Am           Dm
I wish I had missed the first time that we kissed
      Am        E        Am   Dm

So don't come back for me
                   C
Don't come back at all


C                           G

Who do you think you are?

Who do you think you are?
