Thanx to FatKidsOnMopeds to that I found this:

Intro:      D  |        | Em/D    |  A
            D  | D E F# | G  E  B |  A 
             
D
I couldn't figure why
                          F#m
You couldn't give me what everybody needs
Bm                                   F#m
I shouldn't let you kick me when I'm down
   Em A7  
My ba-by
G/D
I find out everybody know that
A/C#              A 
You've been using me
Em7
I'm surprised you
A
Let me stay around you

D
One day I'm gonna lift the cover
    F#m 
And look inside your heart
Bm
We gotta level before we go
    Gm7
And tear this love apart


(CHORUS)
           D
There's no fight you can't fight
     G         A         D 
This battle of love with me

You win again
Bm
So little time
      Em7            A 
We do nothing but compete

           D 
There's no life on earth
   G           A      D  
No other could see me through

You win again
Bm
Some never try
       Em7             Asus4
But if anybody can, we can

And I'll be, I'll be
          D
Following you

1 x C  G  - D
2 x C  G  - (new key Eb)
 
C  G                         Fm
Oh baby I shake you from now on
          Bm                
I'm gonna break down your defenses
       F#m
One by one
          Bm  
I'm gonna hit you from all sides
         E7 
Lay your fortress open wide
A7           G      
Nobody stops this body from
A/F#   A7/E
Taking you

             D
You better beware, I swear
                   F#m
I'm gonna be there one day when you fall
Bm
I could never let you cast aside
    Gm7
The greatest love of all
