Capo on the 3rd Fret
This is a more intricate verson, but I feel it sounds better and is more accurate. 
It's not as hard as the chord diagrams look.

I'll call the D add4, "D/F" during the song   


G                      Dsus4
 You're the boy with a real nice smile
     D/F             G1
But a broken heart inside
                    Cadd9
Give it to a girl, gave it to a girl
                          G
And I think she lost her mind
                      D
Are you giving up and done?
                          G1
Are you through with all this?
                     Cadd9               Em7
Are you tired of the pain?  Torn to pieces

D     Cadd9    D/F   
Can you let me try?

G                      D/F   
tell me it's all right, just for one night
C1                        Csus2
Show you how to feel like, what it feels like.
G1
To be hugged, to be kissed
G                          Cadd9
Yes, I can be that part of you
     Dsus4
I'll try my best

G  D  D1  C1

G                    Dsus4       
 I'm the girl, I can make you smile
      D/F           G1
And I promise to be true

Give it all
Cadd9                              G
Give until there's nothing left to lose
                                D
Don't say you're giving up and done
                              G1
That you're through with all this
                         Cadd9              Em7
Yeah you're tired of the pain, torn to pieces

Tell me it's all right, just for one night
G1                         Csus2
Show you how to feel like, what it feels like.
G1
To be hugged, to be kissed
C1
Be thought of and to be missed
G                     
I can be that part of you
D
Let me be that part of you

   G                       D/F      
I see that you're breaking, your heart is breaking
          C1
Here's my hand if you'll take it
Csus2              G1               G
We can make it out of all this mess, no more stress
                      Cadd9
I can be that part of you, I'll
Dsus4
try my best

G1  Cadd9  G  Dsus4

G1            C1
Give me your heart, I
G
don't want a piece or a part, I want it all
    Dsus4
want you to fall
G1        Cadd9
Just a litt-le bit
G
Take that leap of faith if you want to
D                                     Em
Don't let that broken heart haunt you

D      Cadd9    D/F

I see that you're breaking, your heart is breaking
          C1
Here's my hand if you'll take it
Csus2              G1               G
We can make it out of all this mess, no more stress
