After reading the private conversation, I believe that John still has feelings for Abigail. I think that his feelings are not as strong as they were when she was still working for him. I believe this because when Abigail speaks poorly of his wife, he defends her and gets very frustrated with it. He truly cares about his wife no matter what happened with Abigail. I think he still has feelings for her because he admits to looking up to her window at night.
