mdd, I know of one case like that. And the husband was a mentch, freed his wife (who ended up marrying a non-Jew) and was blessed to meet a wonderful woman. They now have a beautiful daughter together.
That’s it. ONE case. 99.9999% of divorces are wanted.
Verbal abuse is often hard to prove. Problems in a marriage are often hard to prove.
What does a man have to gain by trapping his wife in a marriage she doesn’t want? Absolutely nothing but pain to both of them.
