[Verse 1]
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
[Hook]
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. Hope it helped.
