My reaction to the ending of the book was a lot of confusion. The fact that Anse came back from town with a new wife was shocking to me. My idea of how this situation could possibly make sense is as follows. I think that Anse had an affair with Addie's sister years ago so Addie is very mad at her. Addie was so mad at her that her and Anse never told the children about her and Addie told people she "has no family". Therefore, Anse is already familiar with her and is sexually attractided to her. This is also why he knew to go to her house to get shovels. Wether this is what happened in the past or not, this is how I made sense of the situation.
