I’m asking about a woman’s maintenance during the iddah if she leaves the husbands house due to

I would like clarification on the Islamic ruling regarding a husband’s obligation of maintenance during the ʿiddah period. If a woman requests a divorce due to her husband’s disloyalty, emotional neglect, and failure to uphold her Islamic rights, and the husband then issues a divorce, is he still obligated to provide maintenance during her ʿiddah if she chooses to stay at her mother’s home rather than remaining in the marital home—especially if she left the marital home due to his actions and the negative impact on her mental and emotional well-being resulting from his failure to fulfil his responsibilities as a husband? Additionally, if there was an agreed-upon amount of maintenance during the marriage that the husband failed to provide, can the wife request this amount as part of her Islamic maintenance during the ʿiddah? If he did not give it during the marriage, is he still obligated to pay it? Finally, if the wife left the marital home during the ʿiddah and did not return, does this affect the husband’s obligation to provide maintenance during that period?
