I am so sorry to hear that he is still struggling to feel something. When I had lost my emotional connection with my wife it felt horrible and so empty. I wanted to do anything that would make me feel something...anything again.
The thing that confuses me with him though is that you are trying the best that you can to connect with him and it is still not enough?
Ali you continue to be in my prayers. I keep praying that your H will finally see that you are giving so much to him and that he will feel the love you have for him.
