Joseph, you are to be commended for your determination. You’re quite young but it’s interesting that the women and wives of many orthodox pre and post holocaust families did not adopt the tznius standards of today’s orthodoxy. This would even include the daughters and wives in chassidic families; of prominent rabbis; and even Rosh Yeshiva. Many if not most mothers of post war baby boomers did not cover their hair until their children started to marry in the early 1960’s and it just progressed from there. Someone once asked one well-known Rosh Yeshiva why his wife didn’t cover her hair. His response was something like: “So, do you want me to divorce her?”
Keep up the good fight.
