Is a woman entitled to seek divorce if she is unable to adapt to her husband and suffers from unhappiness in her marital life, especially if the husband's family is dysfunctional and her husband rarely approaches her, and she fears the impact of this on her parents, and regrets her insistence on this marriage?

Divorce is originally disliked (makrooh), and a woman is prohibited from seeking it without a legitimate reason. It appears that your marital life does not contain anything that warrants seeking a divorce, especially since your husband is loving and keen on you. Beware of the whisperings of Satan, who seeks to cause discord between spouses. We advise you to cooperate with your husband in obeying Allah and adhering to the Sharia, and to reach an understanding with him regarding intimate matters, and to rectify any shortcomings on your part in good companionship, beautifying yourself for him, and showing affection towards him. If your husband does not keep you chaste, then in this case, it is permissible for you to seek divorce or khul'. Do not rush to seek divorce unless all means of reconciliation have become impossible.
