I think a woman without a husband, in 'Bible' times, would still be in her father's home, and would be subject to her father and would ask him. (obviously not in the usa, or today in many places).
also, one very uncomfortable note (most will probably say 'subjective'; that's okay) In all my years, in all my travels, in all my searching and learning and seeking God's face to know the truth, I have never seen a
divorced woman(who was willing to be divorced) able to faithfully(reliably)separate what is true from what is false in sometimes important revelations of, ideas about, and general scriptural discussions. t to be his comes out in conversations, speeches, teachings, radio, tv, church, and synagogue - i.e. no matter where she is, my observation is that what she says cannot be trusted much more often than 'usual'. I haven't met or seen an exception to this yet. (most will probably say 'subjective'; Yhwh knows.) . Admittedly, in today's society including religious groups, it is rare to find someone, man or woman, who simply always tells the truth and is always loyal to God.
there's a lot more in Scripture concerning this, enough for several threads.... one at a time (some are already started, i think) .
