Reb Eliezer, the yetzer hora never rests and never lets people become immune… Look at the secular world, the genders intermingle casually and the rate of divorce is at 50%, and for those who are married there are many options within marriage… And just look at how these teens live coming from these freely mixing environments…They have immunity, right?
A big part of why the divorce rate is lower in the Chassidishe community is because the majority of people in our communities don’t mix as much as in the non-Chassidishe communities. And in fact, married couples who are on the edge of Chassidish, having grown up in Chassidishe families and became more modern, often eat Shabbos and Yom Tov at each other’s houses and eat out in restaurants together, and their divorce rate is much higher than regular Chassidishe couples.
