cantoresq, your initial response precluded tochacha, and was worded as if tochocha doesn’t exist. Tochacha demonstrates that it is NOT only between them and G-d. Every Jew is responsible for the spiritual well-being of every other Jew.
Why do you assume if another woman gave her tochacha, they would be non-responsive? The “very technical requirements in giving tochacha” require that it be given unless one is CERTAIN it will be disregarded. See Sefer HaChinuch perek 239.
