I'll take a stab at this, but I'm no expert, so keep that in mind. My comments are inline below.
My Heart Says Sorry
VERSE 1
I wasn't thinking
And I don't know what came over me
I got carried away again
But, you know me, I'm easily led astray
I do remember listening to my heart
And it said, Oh no no
Come on, All loving is good loving
Nobody needs to know
CHORUS
See it's ain't all on me
But I'm here to apologise
My heart says sorry
And so do I
VERSE 2
And the next thing I know
My heart is serenading
Some peroxide poodle girl
And his Does "his" mean your heart? How about "its" instead? beat is racing
He stole kisses from another's lips
An unforgivable thing
It's no excuse that we was seduced
By the forbidden fruit
I assume the "we" in line three is meant to be "he". And again, we have this mysterious "he". If it's meant to be the singer's heart, it comes across odd to me...your heart stole kisses?
CHORUS
See it's it ain't all on me
But I'm here to apologise
My heart says sorry
And so do I
VERSE 3
I tried to tell him, Walk away
But my hearts heart's will is strong
Now I ain't sayin nothing
Except that we was wrong
Again the "he" I'm not sure about, but thinking it means the singer's heart....
But can't you see how you made him feel?
All bigged swelled? I don't think "bigged" is a word up with pride
Got him thinking he enough love for you
And then plenty more besides
The verse above sounds like the singer is blaming his love interest for the problem.
CHORUS
See its it ain't all on me
But I'm here to apologise
My heart says sorry
And so do I

Thanks for marking the verses and choruses clearly. That makes it easier for an easily confused brain like mine.
I have a general recommendation for you...right now the song strikes me as someone kind of whining because he strayed and now he's sorry and wants his lady love to forgive him.
If you want to stick with a story line of a cheating man, I suggest making him a more likable by making him more remorseful. Right now, he seems to be excusing himself, so I'm left believing he's just going to keep right on cheating and expecting his sweetheart to keep forgiving him. Rather, make him realize he's made a big mistake and he's going to use what he's learned to mend his ways so it doesn't happen again. And he should take full responsibility for his own actions, not blame his honey.
Alternatively, if you want to paint a picture of a man who is irresponsible, I recommend his attitude be one of "I just can't be faithful, so honey, don't count on me. I cheated once and I'll do it again, so you would be well advised to look elsewhere for a dependable man." Something like that.
Hope something here proves to be helpful to you.
