than I've done by you", means You've treated me with more respect, friendship, love, than I have treated you. That part
seems pretty straight forward to me.
You know I interpret that line differently...to mean that "you have benefited from this relationship more than I have"...so it is sort of the opposite of how you are interpreting it...hence the I'm going back home...
I'm sorry. I have to stick with my first impression. I've looked at it again, and keep coming back to the definition of "Doing good by sombody".
He left St. Louis, "In th midst of a storm, he'd rather forget." He then says, "I'd rather pretend it came to an end, 'Cause you wern't
the woman I thought I once met." The storm was a big fight, that made him want to leave. And in his pride, he decided she wasn't
the woman he thought he knew. But then goes on to admit doubts, and regret. The darkness of the road, being alone, not getting
a ride, forces him to deal with these thoughts. "Black Throated wind, keeps on pouring in." The night wont let him alone. His thoughts
turning back to the woman he left. "And it speaks of a life that passes like dew." Life is too short to not be happy, to experience love.
And that realization forces him to see, "You've done better by me, than I've done by you". He realizes more, of the futility of trying to run
from your pain. "You carry your pain wherever you go." He realizes what he has to do. "So I give you my eyes, and all of their lies."
That suggests he want her to take him back, with all of his problems. And asks forgiveness. "Please help them to learn, as well as to see."
"The black throated wind Keeps on pouring in, With it's words of a lie that could almost come true." More of a hopeful tone.
"Ah mother night, here comes the light." He's made a decision. The next line is the telling line. "I'm turning around, that's what I'm gonna do."
"Goin back home, that's what I'm gonna do." He finaly comes to the conclusion he has to go back to his love. "Cause you've done
better by me, than I've done by you." It's a typical story of a head strong man who left after a fight, convinced he was right, but
the road, the dark loneliness, and the night, made him realize his mistake. When he says he's going back home, that means to the
woman he left. Sorry if that's long winded. I truly love this song. It's a classic love story.
I can't come down, I've been set free.
Who you are, and what you do,
don't make no difference to me.
