[Verse 1]
A E
I'm sorry for the times that I left you home
F#m
I was on the road and you were alone
D
I'm sorry for the times that I had to go
A
I'm sorry for the fact that I did not know
A E
That you were sitting home just wishing we
F#m
Could go back to when it was just you and me
D
I'm sorry for the times I would ne-glect
A
I'm sorry for the times I disrespect
A E
I'm sorry for the wrong things that I've done
F#m
I'm sorry I'm not always there for my sons
D
I'm sorry for the fact that I'm not a-ware
A
That you can't sleep at night when I am not there
A E
Because I'm in the streets like everyday
F#m
I'm sorry for the things that I did not say
D
Like how you are the best thing in my world
A
And how I'm so proud to call you my girl
[Hook]
A E
I understand that there's some problems
F#m
And I'm not too blind to know
D
All the pain you kept inside you
A
Even though you might not show
A E
If I can't apologize for being wrong
F#m
Then it's just a shame on me
D
I'll be the reason for your pain
A
And you can put the blame on me
A E
You can put the blame on me
F#m
You can put the blame on me
D
You can put the blame on me
A
You can put the blame on me
A E
Said you can put the blame on me
F#m
Said you can put the blame on me
D
Said you can put the blame on me
A
You can put the blame on me
The song follows this pattern throughout. Hope it helped.
