Won’t the guy be in jail? So, she can’t literally still live with him.
I’d leave but I think that I can guess why the woman remains.
Whereas in Catholicism, if we can’t get our marriages annualed we at least have the option to leave and live a celibate life, some fundamentalist women don’t have that option. If they don’t remain in the marriage, doing their utmost to follow thier hubby’s will, then they are seen as failing in their faith.
I even found a website a long time ago that basically said that to disobey the husband is to somehow disobey Christ. This extreme is not the normal type of submitting that most Christians believe in.
Perhaps that is the background this woman is from.
