Husband seems unhappy but I don't know how to help him?

Hard times can affect people in many ways. Sometimes it is difficult to trust in someone and believe that things will work out. If your husband is very angry, he may be afraid that he will lose control if he starts to vent. Tell him you love him. Take care of yourself. Think positive and don't pressure him to open up. Try to make time for intimate moments, and wear a perfume he likes. Let him know how much you appreciate him. You need to rebuild the trust you both lost during the vasectomy and depression. It might help to get counseling.
