Who is The Female Ghost from The Great Divorce and what is their importance?

Many of the characters choose to be left out of the holy bright procession because they cannot shed their earthly pain and vices: they are archetypes of personalities in our world that are addicted to their burdens. The Female Ghost wants to see her husband Robert, whom she controlled during Earth life. She used him to satisfy her needs and didn't respect him as a separate person. Robert is now a Bright Person and the female ghost holds no dominance over him. Her controlling issues cannot exist in Heaven. She has to surrender all ego and control away before she can become a bright person.
