Mrs. B . What you state is unfortunately no longer really true today. The chassidic world unfortunately is rapidly catching up to the rest in terms of divorces. I am not going to post here the things that I have read or heard, but unless one wears blinders, one knows that things have changed a great deal. That is not to say that the chassidish way that you describe does not work well for many people. But even thirty-five years ago, chassidim were surreptitiously going for marriage counseling of a specific nature, and I know this because I dated a frum therapist whose clientelle was ALL chassidish. Without breaching doctor/patient confidentiality, I was told eye-opening things about problems in chassidish marriage, and that was a long time ago. Things have gotten more out in the open, and divorce, while not desirable, has less of a social stigma than it once did.
You write that your husband would not appreciate your inviting your friend and her husband to a shabbos meal. My husband would not appreciate it if I were to REFRAIN from inviting couples to our Shabbos table. So you see it really is a matter of one’s perspective. Hachnossas orchim is a very huge mitzvah D’Oraisa. I totally respect your position on this, but it is a derech that I find very limiting.
