Notpashut, the story I heard marginally differs. The satmar rebbe complained about 8 dates, and quoted the passuk “Katzti bechayay mipnei bnos bnei ches”, a pun onthe word “ches” meaning the Hittites and the number 8. Rav Bik replied with his now-famous line of the difference between a mesader kiddushin and a mesader gittin.
I heard a statistic that 85% of today’s divorces are preventable. It’s just a question of people not willing to make it work. The other 15% of course are the hidden problems etc.
