How can a woman overcome the pain of her divorce from her ex-husband who wronged and humiliated her, even though she is married to a righteous man and has been blessed with children, and does her love for her first husband still affect her current life?

You must fear Allah and be grateful to Him for His blessings. For with gratitude, blessings increase, and with ingratitude, they vanish. Show gratitude for the blessing by treating your husband well, turning your heart away from your ex-husband, occupying yourself with your husband's rights, and drawing closer to your Lord. Be content with what Allah has decreed for you. For in the heart there is an unease that can only be calmed by turning to Allah, and fires of regret that can only be extinguished by contentment with His command and decree, and patience in that.
