How do you treat male menopause?

My husband is grumpy, irritable, moody, changes his mind about vacations, and even cant decide what he wants for dinner. He has no drive anymore, is not motivated. He doesnt get things done around the house like he use too. He is always feeling sorry for himself, and now he even dislikes his current job. He is 57 years old. He doesnt want to go out with our friends anymore, hes just too tired or not in the mood. He is upset about the weight he gained, and is loosing his hair which has him upset too. He may be loosing his hair, but Im loosing my mind! How do I cope with all of this? Im on hormone replacement myself, and it has been wonderful. What can he do, and how do I handle all of this?
