The song, to me, seems to have two different meanings.
For me, the first part of the song is about leaving an apartment you shared with an apartment due to a split, hence the "was it you who should have stayed", etc, similar to the theme of Owen's 'The Ghost Of What Should've Been', but the second part seems to be more about actually leaving as in dying, hence all the ghost lyrics. It's definitely a haunting track though.
