Cover art for Walk Away lyrics by Christina Aguilera

To me this song could as well be about being the other woman. How "Artificially sweet" it all was to begin with and how she nothing in return got - of course for the reason that he already had another. It seems like this song is about trying to break free without any luck. Being down on your knees only wishing that the pain, anger and frustration would go away. Even though she tries to go away she keep going right back to one thing that she need to walk away from (to quote to song).

How bad this relationship is for her and how she really need to get out of this addiction.

("addicted to your allure")

Of course this is just my interpretation of this amazing song.
