There a few misconceptions that are repeated in the above comments.
1. Therapists – weirdos. There are weirdos who are electricians, insurance brokers, journalists, doctors, any other career, even rabbonim. And there are plenty of each of those categories who are nice, ethical, moral people who are extremely conscious of what they know (and can practice) and their limitations.
2. Therapy for who, for what. True, everyone can benefit from therapy. But let’s ask the first question that any therapist should ask a newcomer client. “What problem brings you here?” If one cannot specify an issue they wish to resolve, nothing will occur in that therapy besides, perhaps, learning to use insight, and some character improvement. These are wonderful, but are luxuries. Here is the cost factor.
3. Premarital therapy. I have not a doubt that some people need this. I suggest an alternative. Premarital education. I do not refer to the needed chosson and kallah classes. Those halachos are crucial to living as a shomer Torah umitzvos. I refer specifically to learning how to communicate, how to disagree respectfully, how to grow into a bond of safety, spirituality, and true love. Despite the denial I heard from those who do such teaching, it is rare to find this being done properly. And maybe the time and place is much before engagement, even dating. Do our yeshivos, schools, and seminaries do any of this? Don’t all answer at once. What difference should it make if the one offering this guidance and teaching possesses letters after their names or the titles of Rabbi or Rebbetzin before their names?
There is a sefer from Reb Klonymous Kalman of Piescecznia (author of Chovas Hatalmidim) called ??? ????? ???? in which he describes a proposed self help mussar group with rules and guidelines. This idealogically resembles what was initally suggested by Reb Yisroel Salanter. It proposed a lifestyle that involved a heavy amount of introspection that was brutally honest, where others were permitted to offer their help and suggestion to overcome the challenges of midos we face all the time. This is an example of an idea that can be implemented into our educational system which would obviate the need for professional intervention later. Sadly, nothing of this sort goes on, and we are left to our own guess of what midos are worth emulating and fixing into our characters.
