Is there a reward for me for marrying a woman of average beauty after it became difficult for me to refuse her, and for my patience with my feelings towards her and not showing them to her, and what is the solution?

In Islam, a wife is chosen based on specific criteria, and pity is not one of them. Since the marriage has already taken place, you must treat your wife well and take good care of her, for the Prophet, peace and blessings be upon him, said: "The best of you is the best to his family, and I am the best among you to my family." You must treat her kindly, as Allah Almighty said: "And live with them in kindness. For if you dislike them - perhaps you dislike a thing and Allah makes therein much good." And according to the Prophet, peace and blessings be upon him: "No believing man should hate a believing woman. If he dislikes one of her characteristics, he will be pleased with another." Marital life is not always built on love alone, but on Islam and good lineage. Your decision to marry her with the intention of safeguarding her chastity and your own, and your continued commitment to that, is a righteous deed for which you will be rewarded.
