Ok. I don't really know if it works for everyone, but it fits just fine for me, at least 
think this is the basics clear chords, without all those things Robert does, those 
and stuff.

If you want you can use C/B whether than G.

Verse 1
                  C G
Should never think
                  Am G
What's in your heart
                  F G
What's in our home
                  Am G
So I won't

(And it goes on like this. Just changes in this part):

G                  F
It's the one thing that I know
        G             Am
Once I put my coat on
      G                      F
And I know this is all wrong
                       G
She's standing outside holding me
      Am                    G  F
Saying  Oh please, I'm in love
        G
I'm in love

(Then it goes back to he same chords as the first verse)

Hope have done something good. ;D
