One reason why there are more divorces around Tishrei time, and after frum convention season is the lowering of the usual boundaries. When a husband and wife are seperate for eight weeks (wife in a bungalow and husband in the city), the relationship weakens. At frum conventions there are tremendous amounts of male/female mingling and interaction.
Quite simply: Ain apitropis le’arayos. Therefore, both summer bungalows and frum conventions MUST be eliminated.
