Should a husband divorce his wife who requested a divorce due to his treatment of her and who has been living with her family for seven months, and what are her legitimate rights in this case, and is she entitled to maintenance for the past period?

If the wife insists on divorce, there is no impediment to divorcing her. She is considered disobedient (nashiz) and is not entitled to maintenance due to her departure without permission. Furthermore, some scholars are of the opinion that she has no right to maintenance during her iddah (waiting period).
