[Verse]
Bm                            D 
I know I can't take one more step towards you 
A                              Em 
'Cause all thats waiting is regret 
Bm                               D 
And don't you know I'm not your ghost anymore 
A                              G   D/F# 
You lost the love I loved the most
[Pre-Chorus]
Em           G    Bm      A 
I learned to live half a life 
Em           G             D5/A  A 
And now you want me one more time
[Chorus]
D                           A 
  And who do you think you are? 
                        Bm 
Running 'round leaving scars 
                        G 
Collecting your jar of hearts 
 Gm            D 
Tearing love apart 
                      A 
You're gonna catch a cold 
                          Bm 
From the ice inside your soul 
                     G 
Don't come back for me 
Gm                    D   A/C# 
Who do you think you are?
[Verse]
Bm                         D 
I hear you're asking all around 
A                        Em 
If I am anywhere to be found 
Bm                     D 
But I have grown too strong 
A                          G   D/F# 
To ever fall back in your arms
[Pre-Chorus]
Em           G    Bm      A 
I learned to live half a life 
Em           G             D5/A  A 
And now you want me one more time
[Chorus]
D                           A 
  And who do you think you are? 
                         Bm 
Running 'round leaving scars 
                        G 
Collecting your jar of hearts 
 Gm            D 
Tearing love apart 
                      A 
You're gonna catch a cold 
                          Bm 
From the ice inside your soul 
                    G 
Don't come back for me 
Gm                    D 
Who do you think you are?
[Bridge]
Bm          F#          Bm7/A  E/G# 
It took so long just to feel alright 
  Bm            F#           Bm7/A         E/G# 
Remember how to put back the light in my eyes 
   Bm          F#             Bm7/A          E/G# 
I wish I had missed the first time that we kissed 
        Bm        F#      Bm7/A   E/G# 
'Cause you broke all your promises 
     G 
And now you're back 
                 F# 
You don't get to get me back
[Chorus]
D                       A 
  Who do you think you are? 
                        Bm 
Running 'round leaving scars 
                        G 
Collecting your jar of hearts 
     Gm            D 
And tearing love apart 
                      A 
You're gonna catch a cold 
                          Bm 
From the ice inside your soul 
                        G 
So don't come back for me 
Gm                  D 
Don't come back at all  
                          A 
And who do you think you are? 
                        Bm 
Running 'round leaving scars 
                        G 
Collecting your jar of hearts 
 Gm            D 
Tearing love apart 
                      A 
You're gonna catch a cold 
                          Bm 
From the ice inside your soul 
                     G 
Don't come back for me 
Gm                  D 
Don't come back at all
[Outro]
Gdim7               D 
Who do you think you are?

Who do you think you are? 
Gdim7                  D 
Who do you think you are?
