I tried to keep this as simple as possible. I'm sure it's possible to find more 
accurate/complicated chords that work at least as well, but these seem to work for me.

Whole song, lyrics and chords all the way through.

Intro: G D C G

G                                            G7
Something grew out of nothing at all
           G                                         C
The way things sometimes do
       G                                G7
It grew so big that before I knew it
               G                                 Am7
It had outgrown me and you

                  G                           C
I am the boy with two hearts
                  Bm                       C
I am the boy with two hearts
                          G            C
And there is only so far
           Bm                       C   Am          G            D         C         G 
I can be stretched before I come apart

G                                       G7
I know I?m not much fun to be with
          G                                     C         
But you love me all the same
            G                                   G7
And some day hopefully I can just go back 
         G                       Am7
To being myself again


                  G                           C
I am the boy with two hearts
                  Bm                       C
I am the boy with two hearts
                          G            C
And there is only so far
Bm C   Am    Bm  Cmaj7   Am7     Dsus4   D
I can be stretched before I come apart

G     D      C       G       D      C

                  G                           C
I am the boy with two hearts
                  Bm                       C
I am the boy with two hearts
                          G            C
And there is only so far
           Bm                       C   Am          G            D         C         G 
I can be stretched before I come apart
