Please make sure your husband is not in pain. His sitting there with his head in his hands makes me wonder, as this is what my brother did when the pain in his mouth and head was too much. If he is hurting, go back to the doctor and make them look and look and look. If not, please remind him that eating is not everything. He is and his being with you is the most important thing of all. My brother was always very good about our eating or cooking around him, though I now the guilt you feel all too well and it took everything I had to swallow food myself. I STILL feel guilty and he's been gone over a year. But, he didn't care. He was just glad to be there and I guarantee you, if he had the choice to stay with his family and not eat, or pass on, he would still be here today. Find something new to enjoy together. Just enjoy each other. It's the most precious thing you have.
Best wishes,
Tonya
