I find it interesting to read the comments of lay people, however intelligent, about issues that are intricate and complex, but totally out of their domain of expertise. I am not against consulting a Rav, but I am skeptical that there are many whose advice is useful in such situations. Rabbonim are rarely trained or experienced in providing guidance on matters of shalom bayis. The role for a Rav is to provide support, referral to professionals and needed community resources, and a helping hand (that is carefully restricted from intervening or taking sides with anyone).
The generalizations in earlier comments are as entertaining and amusing as they are dangerous. Are all children of divorce “damaged”? I hope not. Their lot in life has additional challenges due to divorce. But an intact family with poor shalom bayis is also damaging. Is divorce the answer? Sometimes yes, and sometimes not. Only professionals can help decide (with syatta dishmaya, of course).
Someone noted that the therapist and Rav do not make the decision. That is correct. But the professional guidance to make a decision properly, without falling prey to the overwhelming emotions of the crisis is critical.
The divorce process is also complex. There are many aspects that are not common knowledge, and require professional guidance. There are many frum professionals who know the courts, the lawyers, the to’anim, and batei din. They are useful in helping someone going through this process in utilizing the needed resources. It’s easy to be misguided, even by people who mean well and are otherwise nice, respectful people.
Someone said, “People marry out of love, and divorce out of hate.” There are heaps of negative emotion when marriages split, and it is a challenge to deal with all this. Get help and guidance. Don’t assume a Rav, with all his smichos and areas of halachic expertise is learned and experienced in this parsha.
