[Verse 1]
A# F
I'm sorry for the times that I left you home
Gm
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# F
That you were sitting home just wishing we
Gm
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# F
I'm sorry for the wrong things that I've done
Gm
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# F
Because I'm in the streets like everyday
Gm
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# F
I understand that there's some problems
Gm
And I'm not too blind to know
D#
All the pain you kept inside you
A#
Even though you might not show
A# F
If I can't apologize for being wrong
Gm
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# F
You can put the blame on me
Gm
You can put the blame on me
D#
You can put the blame on me
A#
You can put the blame on me
A# F
Said you can put the blame on me
Gm
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
