Plenty of women don't report rape, beatings and other physical assaults, even when it's 100% the fault of their boyfriend/spouse. Common knowledge among law enforcement. Most of these women grew up with daddy issues and on some level like the uber-authority/controlling mannerisms of their male companion, while these women also exhibit the typical tendencies of a life of "sleeping around" - lack of submission, pride, feminism. They go from one extreme (enjoying being controlled) to the other (don't tell me what to do). Except for the miracle of graces from God, they are emotional yo-yo's whose childhood destroyed any chance at a normal life. So, yes, these types of women exist (and the % grows day by day, as the family continues to evaporate from existence in our modern world).
That makes sense. I can imagine women becoming so warped by sin that they are emotionally disturbed like this. As you say, it becomes more and more likely as society continues to degenerate. I cannot see, however, how a husband of such a woman would have a duty to beat her. Obviously, a man should not marry a woman like this in the first place, but if he did, wouldn't it be his duty to do whatever he could to bring healing to her damaged soul? Beating her seems like it would merely reinforce her unhealthy enjoyment of being over-controlled.
The main reason that the husband is the head of the family is that men are generally more reasonable than woman and the man should govern his family by reason. In the situation that you describe, wouldn't the duty of the husband be to use his reason to bring order to the disordered emotions of his wife? He needs to teach her how to obey and respect him in a balanced way, without this bouncing between extremes. I just don't see any place for beatings in this scenario.
What advice would you give a man who had the misfortune to end up married to a woman like this?
I just had a thought. Would you say that this was the problem with the wife in Shakespeare's play
Taming of the Shrew ?
