why does janie decide to leave with joe?

Janie's husband Logan treats her poorly, she's nothing more than a housekeeper and work horse. When Joe comes along, he flatters her and treats her like she's worth something. He asks her to go away with him, and she's tempted but not convinced. She gives Logan one more chance and warns him that she's considering leaving. Unfortunately, he's more worried about who's going to move manure than he is about anything else. Janie throws a few insults away; Logan threatens to kill her; and then off she goes with Joe.
