The fact that divorce was accepted in the Protestant  world  made it acceptable in the Jewish world also. Divorce would be the classic example of where shaming someone worked very well. People would whisper "she is divorced" under their breath as if some horrible unspeakable monster had been let loose.  Poland is a mainly Catholic country  the fact that divorce was considered as a horrible demon had the effect on Jews that Jews also simply did not get divorced except under extreme circumstances.
