At first, I thought it was about a break-up, but then listening more, I think it's about her loved one dying and her moving on, but I'm not sure.

I think it is about her loved one dying as well. It is far too raw and revealing to be a breakup song. I would never lay all that out there to someone who could leave me feeling that way, ya know what I mean? =) It's just my opinion, clearly, but I totally agree with the death theory.
