I had a husband much like that one time. But he too had his issues. He had ptsd from vietnam and was addicted to his meds and beer. Therefore it was impossible for him to show me desire phyiscally and alot of times emotionally but deep inside I knew he loved me even with all that. The last words he spoke was to me. Even though we were apart at that time and he was remarried he told me he loved me. There is alot more to that story but you sound like you know deep inside he still loves you.
