Hmm. I would like to posit a more sinister meaning. This a man trapped between two loves; the "good woman," to whom he addresses the song, and the "dark lady" (freely stolen from Shakespeare's sonnets) who keeps him hanging, no doubt laughing all the while. One person who loves him and who he loves, the other he also loves but is merely using him.
