Shlucha, I agree that women took over halakhic issues at home (at least in mine). My only involvement is to convince girls that in a machlokes between BY and Mom, we pasken like Mom.
But this is not due to men being outside of home, after all, other than shabbos shul, the husband is hopefully either available on the phone or is at home. It is more due to the expanded women’s education – as they need to ask husbands less, husbands gladly switched to learning esoteric subjects that do not lead to any daily responsibilities.
