Well, parrotpie, I agree with you for the most part, but I feel as though you're missing a big part of it. However, songs are always up for interpretation; that's what makes them so great. Here's my thought: This is a guy trying to tell a girl that he loves--perhaps in a romantic way, perhaps not--that the guy she is with is not only bad, but abusive. He feels that he is better for her than the current guy--obviously touching on the romantic possibility now. It's the classic story of a girl staying with an abusive guy (mental or physical) while a perfectly good guy--who understands her--is just sitting there, and too many times is the one who has to pick up the mess that the aforementioned douche bag created. We see this through lyrics like, "I touched that place on you, and all the while...; I brush your hair." The girl doesn't want to believe the harsh reality that stares her in the face: "with your naked excuse you confuse your misuse." eventually the guy has an epiphany: "So it finally dawned on me yesterday morning, I just can't stare; what makes you think i should care what he'll do..." the pieces are beginning to all come together in his mind. She's just another girl who is going to be complacent in misery--or as trent reznor put it, "happiness in slavery." He realizes that this is the life she has chosen, and shows no plans on changing it in the near future; thus, he makes peace with the fact that he must move on, and let her make her mistakes; let her be happy in slavery.
