Janie did not make the right decision in Chapter 4. She had no reason to leave him. If she left him because of the way he treats her then its fine, but she seeks love because she probably never had that before. So being curious is very interesting way to go through relationships , but it is not something you can put a man through.
I would not have done the same thing. I would not have left. I would not listen to people and follow their ideas, so situation would not have happen.
