Dr. E:. The Beis Yaakov girls today are not dating for shorter periods or getting married younger than the Beis Yaakov girls of 10 or 20 years ago have. In fact, if there’s been any changes in recent years compared to their mothers or older sisters, it is that they’re dating longer and getting married later.
So if the divorce rate is up currently, it clearly is not a result of them dating shorter than before or getting married younger than better. Indeed the opposite might be the case.
So we might do well considering to have the couples date shorter and marry even younger.
Further proof to this is that the Modern Orthodox community, which dates notably longer and gets married notably later, has a significantly higher divorce rate than the Yeshivish and Chasidic communities.
