I think the WT writer must have taken that story from one of the older publications. In the 50's I remember hearing an experience like that at one of our circuit assemblies, and I thought it was just wonderful that the husband FINALLY came into the truth due to the long-suffering of his wife. It seems like society in general back then didn't take spousal abuse as seriouslly as we do now. I think many women didn't have as many options as they do today. It wouldn't have been as easy to leave an abusive husband as it is now. Today there are support groups for victims of domestic violence. Also women today tend to be better educated and can function on their own without have to remain in an abusive situation.
My own daughter was a victim of spousal abuse and ended up divorcing her JW husband. This was about 11 years ago. She showed the elders her bruises, and they actually supported her in her decision to leave her husband.
