Was listening to the song today and thought these chords fitted very well :) 
Enjoy and please comment below if there is anything you would change.


Capo 1
Standard tuning.

D , A , Em , G


D             A              Em
  What do you do when you're stuck,
            G
Because the one that you love,
D    A          Em
 Has pushed you away,
              G
And you can't deal with the pain,
D               A         Em
 And now you're trying to fix me,
G
Mend what he did,
D             A              Em      
I'll find the piece that I'm missing,
    G
But I still miss him,
D      A    Em          
I miss him, I'm missing him,
G    D           A             Em              (G) Optional
Oh I miss him, I miss him, I'm missing him 


           Bm             A     
And you're sitting in the front row,
         D        G
Wanna be first in line,
Bm             A
 Waiting by my window,
       D           G
Giving me all your time,
D               A
You could be my hero,
Em              G
If only I could let go,
D             A        Em
 But his love is still in me,
G              D       A
 Like a broken arrow.  Ooh oh
A              D             Em
Like a broken arrow.  Oh ooh ohoh


D         A           Em
 He's the thorn in my flesh,
G
That I can't take out,
D     A           Em
 He's stealing my breath,
G(One stroke)
When you're around,
D              A           Em
And now you're trying to convince me,
G
He wasn't worth it,
D       A        Em
But you can't complete me,
         G            D
He's the part that is missing,
D      A    Em          
I miss him, I'm missing him,
G    D           A             Em              (G) Optional
Oh I miss him, I miss him, I'm missing him 


           Bm             A     
And you're sitting in the front row,
         D        G
Wanna be first in line,
Bm             A
 Waiting by my window,
       D           G
Giving me all your time,
D               A
You could be my hero,
Em              G
If only I could let go,
D             A        Em
 But his love is still in me,
G              D       A
 Like a broken arrow.  Ooh oh
A              D             Em
Like a broken arrow.  Oh ooh ohoh

Bm 
What do you do,
          A
When your hearts in two places?
Bm                        G
You feel great but you're torn inside.
Bm                    A
You feel love but you just can't embrace it,
     D                      G
When you found the right one at the wrong time.

           Bm             A     
And you're sitting in the front row,
         D        G

If only I could let go,
D             A        Em
 But his love is still in me,
G              D       A
 Like a broken arrow.  Ooh oh
A              D             Em
Like a broken arrow.  Oh ooh ohoh


D       G        D         G   
Ooooohh yeahhhhh oh oh ohhhh
