 C                              G 
I'm sorry for the times that I left you home 
                         Am 
I was on the road and you were alone 
                        F 
I'm sorry for the times that I had to go 
                        C 
I'm sorry for the fact that I did not know 
C                       G 
That you were sitting home just wishing we 
                         Am 
Could go back to when it was just you and me 
                         F 
I'm sorry for the times I would ne-glect 
                        C 
I'm sorry for the times I disrespect 
C                       G 
I'm sorry for the wrong things that I've done 
                         Am 
I'm sorry I'm not always there for my sons 
                        F 
I'm sorry for the fact that I'm not a-ware 
                        C 
That you can't sleep at night when I am not there 
C                       G 
Because I'm in the streets like everyday 
                         Am 
I'm sorry for the things that I did not say 
                         F 
Like how you are the best thing in my world 
                         C 
And how I'm so proud to call you my girl 
C                       G 
I understand that there's some problems 
                Am 
And I'm not too blind to know 
                F 
All the pain you kept inside you 
                C 
Even though you might not show 
C                G 
If I can't apologize for being wrong 
                Am 
Then it's just a shame on me 
                F 
I'll be the reason for your pain 
                C 
And you can put the blame on me 
C               G 
You can put the blame on me 
                 Am 
You can put the blame on me 
                F 
You can put the blame on me 
                C 
You can put the blame on me 
C               G 
Said you can put the blame on me 
                Am 
Said you can put the blame on me 
                F 
Said you can put the blame on me 
                C 
You can put the blame on me 

The song follows this pattern throughout.
