I feel jealous because my husband works closely with female staff at his office. Is that reasonable?

Your jealousy is a reasonable feeling, but handle it with calm and openness, not accusations. The working world often brings men and women together, so what matters is that your husband keeps proper limits in mixing and stays honest. Express your feelings gently: ‘I feel uneasy, can we talk?’ Listen to his explanation before drawing conclusions. Ask for reasonable openness, such as getting to know his work environment, not checking his every step. Your husband, for his part, should be sensitive and avoid interactions that invite suspicion (fitnah). If this jealousy weighs on you, talk to someone you trust. See relationship psychology.
