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