I have asked jws this:
If you saw someone on the street beat up another person, would you call police? (they say yes, they would)
Why is a different when a close family member does that to another family member, especially a spouse or a child?
What does it do to the children to see their parent beat up by the other parent?
I can't say that the abused person gets the idea right away. The psychology of abuse and how people react to it are pretty much the same despite any economic, cultural, or other situations. There are many professional suggestions and places to start and ways that you can intervene online.
Too many religions tell that wife to endure it and may be their husband will become a believer.
1 Peter 3:1 New International Version (NIV)
3 Wives, in the same way submit yourselves to your own husbands so that, if any of them do not believe the word, they may be won overwithout words by the behavior of their wives
But what happens when the husband is already a jw?
The WTS counsel always seem to assume that only a non-jw husband would do this, giving counsel such as this:
In all cases of extreme spousal abuse, no one should put pressure on the innocent mate either to separate or to stay with the other. While mature friends and elders may offer support and Bible-based counsel, these cannot know all the details of what goes on between a husband and wife. Only Jehovah can see that. Of course, a Christian wife would not be honoring God’s marriage arrangement if she used flimsy excuses to get out of a marriage. But if an extremely dangerous situation persists, no one should criticize her if she chooses to separate.
---but what does the WTS consider EXTREME spousal abuse? What would be less extreme spousal abuse that must be endured? What happens to children who see and hear this abuse?
In 2017, the WTS said this showing that an abusive jw husband could be df'd. But what if the elders use 1 Peter 3:1 to "encourage" the jw wife to stay (and they do).
Extreme physical abuse. An abusive spouse may act so violently that the abused mate’s health and even life are in danger. If the abusive spouse is a Christian, congregation elders should investigate the charges. Fits of anger and a practice of violent behavior are grounds for disfellowshipping.—Galatians 5:19-21.
---The WTS hides child sexual abuse and spousal abuse as well. Cardinal rule: We must not make the organization look bad in the eyes of the non-jw world.
