“He would tell Sethe about the last three weeks: catch her alone coming from work at the beer garden she called a restaurant and tell it all”
For some time Beloved had been trying to push Paul D out in order to have Sethe to herself. Now we come to find out that he has been having sex with Beloved? That is the way it comes off to me, she has been using these actions to push Paul D out. It starts with having him sleep in a rocking chair, then in a cold shed like place and basically anywhere to keep him out of Sethe’s bed. But later on in the passage we find him blurting out he wants a baby? That’s in a way similar to Beloved’s goal of having Sethe to herself. If Sethe has his child then he won’t have to leave. All of this seems to lead me to the conclusion Beloved is a metaphor for still being enslaved, never really able to be free from all their ghosts.
