That's exactly it, at least from how I understand the song. Although from my understanding, I think HE was the co dependent of the relationship. And she's talking about not wanting to be the one to enable the dependency.
As for the "I dont want to live on someday" line, I just interpret it as not wanting to live her life for something that MAY happen one day in the future. That she is who she is today because of what's happened to her in the past.
