The other versions weren't completely accurate, so I made this. 

Chords used:
G:      3 2 0 0 3 3
D/F#:   2 x 0 2 3 3
Em      x 2 2 0 0 0
C:      x 3 2 0 1 0
D:      x x 0 2 3 2
F:      1 3 3 2 1 1
Am:     x 0 2 2 1 0

If you'd like you can alternate by playing Em as Em7 and C as Cadd9 in the verses.  
Em7:    x 2 2 0 3 3  
Cadd9:  x 3 2 0 3 3


Standard tuning
Capo 7th fret



VERSE:

G                        D/F#
       You walk into the room

               Em
So perfect but unaware

          C
Making me stop and stare

      G                          D/F#
Every time I heard he broke your heart

Can I just fix you girl?

Show you a different world?

Where I dream of you and me

Em       D     C      
Should I go or wait

Is it too soon, too late

C (one strum)  G
Only my shadow knows


VERSE:

               Em
And now that I got the chance

          C                     G
I see you need to dance on your own

                     D/F#
So I'll wait another day

Maybe another year

I'm gonna be right here, oh

I wish I could say all these words

          C                            Em
All these things that your heart never heard, yeah

Em                         D                     C (one strum)
But I saw the pain in your eyes and it sealed my lips
