Why does the questioner not believe her husband regarding his lack of desire to marry another, despite his repeated assurances, and what is the impact of her recurring dreams about him marrying another on their relationship?

We advise you to treat your husband with kindness and not to pay attention to dreams, and to beware of the whispers of Satan that may spoil your relationship. Preserve the stability of your family by being good to your husband, being keen on his affection, and cooperating with him in obedience to Allah.
