Am I wrong for felling this way about my husband?

My husband and I have been together for almost 20 years. Ive known him and have been dating since we were 16 years old. Weve been married for 16 years. For the past 5 years, my husband has been gaining alot of weight and hes not doing anything to change it. He has a fat stomach that gets in the way, especially during . Sometime during , Imust be honest, I dont feel him inside of me. We change positions, but I admit its not working. I try to encourage him to take walks with me, cause I recently lost 14 pounds myself and I feel great. I cook healthy dishes and sometimes he refuses to eat them. he will go out on his own and buy sodas and eats alot of foods that he knows isnt good for him. When I look at him, he doesnt give me that "wow" like he used to. He told me hes starting to feel that Im not attracted to him anymore. he said that its depressing him. What can I do to make him feel better? What can I do to change the way that I feel about him. i love him, but I do admit that Im not attracted to him..
