What should I do when the earth and my soul have become constricted, in order to mend my relationship with my wife, who is seeking a divorce due to my ill-treatment of her, despite my profound regret and intense love for her, and my readiness to change myself?

You must be patient and supplicate. Try to reconcile your differences through the intervention of wise individuals from your family and hers. Strive to avoid causes of estrangement and discord. If the wife insists on divorce, then consider divorcing her, for it may be the best course of action if cohabitation becomes impossible.
