Am I entitled to live a life free of pain or anxiety, in light of my husband's desire to marry another woman, knowing that I do not fall short in fulfilling his rights, and I have tried to accept the matter to no avail?

We advise you to seek Allah's help and supplicate Him frequently to inspire you with patience and grant you success in fulfilling your husband's rights and treating him with kindness. We also advise you to reflect on the consequences and harms of jealousy, as it may lead to wronging your husband or to divorce and the dispersion of the family. We remind you that your husband treats you well, and this is a blessing that necessitates gratitude and preservation. If you are unable to be patient and fulfill your husband's rights, then there is no blame upon you for seeking khul'.
