Akon - Sorry Blame It On Me Chords & Tabs

I stopped after the first verse and chorus because the song follows the same pattern. 
not sure if this is right it's my first tab. Especially the opening part.


This is the intro when he is talking and the piano is playing I think, it repeats through
E|--3-0-3-3------------------0-----------------|
B|-----------3-0-3-3-1----1----1---1-3---------|
G|----------------------2--------2-------------|     PLAY TWICE
D|---------------------------------------------|
A|---------------------------------------------|
E|---------------------------------------------|

 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. Hope it helped.
