I agree completely. There are ways to deal with this subject without being offensive, even to the “frummest”. It is a delicate subject to discuss with an audience of a classroom. Actually, there is growing pressure to begin the process of preparation for marriage in yeshivos and schools, to focus on the midos needed to manage a relationship. There are many subjects that can be safely addressed, such as communication, consideration for another, the merging of families with different values/patterns/minhagim, etc. If you are among those who are sitting back expecting yeshivos and schools to designate one of their faculty to create a curriculum and to implement it, I hope you are not holding your breath. But there is outside pressure, and I wish it much success.
Meanwhile, the batei din, toanim, and matrimonial lawyers are all very busy.
