Counseling might help and definitely worth trying. However there is also a support group forming for partners in similar situations if you are interested.
Does he have any friends here? Does he have any hobbies? You need to get him out this rut. He needs to let go of his feelings and let it all out. Can you book a weekend away? Or something fun in the evening that you used to enjoy together?
Big hugs to you Kimora. Your husband sounds depressed. I know it is hard on you but I think he needs you more than ever now. Don't give up on him - never give up on marriage. It is always worth fighting for. If you fail, at least you know you tried. Have you spoken to your hubby about this? He needs to see a doctor. Would he go and see one do you think? Hugs x
