D 
To you I'm just the man who let you down 
    G                               D 
The one who never gave you what you need 
     D 
It's true I wasn't always around 
G                                   D 
Back when you were reaching out for me 
  Bm                      F#m 
I know you think I didn't care 
    G                        D  
You say I'm just the hurting kind, 
  Bm                             F#m    
I know you think my heart wasn't there 
        G                               A 
But I'm begging you to think it through one more time 
 
      D                            Bm   
Cause you don't know a thing about me 
   G                         A   
If you don't know how much I miss you 
    D                            Bm 
And you don't know a thing about me 
   G                       A 
Unless you know how much I need to be with you 
    G                     D 
Well I see the mistakes I made 
    G                    A 
The way I acted carelessly 
       D                         Bm  
But if you don't know how much I need your forgiveness 
     G                A           D 
Then you don't know a thing about me  
 
 
If I could just go back and make it right 
And take the tears away you know I would 
I've come to you with no excuse tonight 
Just a prayer that I'll be understood 
You tell me that I'm never gonna change 
I'll always be the same old guy 
You think there's nothing left for us to say 
Before you write me off take a look in my eyes 
 
Chorus 
 
If you don't know how much I need your forgiveness 
Then you don't know a thing about me 
 
No you don't know a thing about me 
You don't know a thing about me, 
Well you don't know a thing about me
