I don’t see why CS is under criticism for this. Everyone I know with marriage problems consults rabbonim. Often the perspective of a daas torah provides solutions and communication skills that the couple hadn’t thought of.
Therapists are trained by the way non jews view marriage. Often they’ll commiserate with the perspective of “what am I getting out of this marriage” and other modern tendencies. I’ve heard horror stories from therapists, very dangerous advice.
Most shul rabbonim double as marriage counselors. That’s just the reality.
People came to rav pam, rav shlomo zalman, and many others all the time with sholom bayis problems. Running to a therapist as a first resort is far more risky than going to a rov who knows at least one of the parties involved.
