The narrator tells of his "goin' my own way attitude." The chorus begins:
Any other woman I know would have tried,
To control me and it would be over.
But, the whole song is about how this stubborn guy, with more than a little self-destruction in him, keeps doing decent things for her and because of her – picking flowers, coming home early, going to church -- "'cause she don't tell me to." This is a subtle step in the dance of courtship and marriage.
The key line, I think, is
An' she don't even know,
That she keeps me lookin' for the next right thing to do,
But she don't tell me to.
