I think that Janie would of just left Joe just like she left the last husband. When enough was enough and she couldnt of taken it anymore she would of said goodbye and went on her way
I must agree with you Cheyenne. Considering her pattern, Janie was almost at her wits end with the way she was being treated and would have still run off with Tea Cake, as he presented a more free and exciting life for her, that was not restrained and allowed her to be herself. She thought she was doing this when she ran off with Joe, and Tea Cake would have simply been the next experiment.
