Husband won't eat anything anymore is 68 and has acid reflux, I am going nuts.?

He likes eggs, toast with bacon or sausage, or french toast with peanut er, and Karo syrup, and sometimes oatmeal and toast for the mornings at lunch he eats sandwiches, peanut er, maybe sometimes roast beef or Spam, but has to eat a dinner meal real early because of acid reflux so he won't eat meat. He says I make the same things over and over but what can you feed a guy that won't eat soups, stews, ceroles, veggies, pastas, no gravies, sauces, or nothing spicy, and no fish. I have made up lists of foods I thought he liked and asked him to pick some. For a time that worked fine till he started to say he couldn't eat meat at night so now what's for dinner? I tried the bean dishes he used to eat but now he says he is tired of those. When I ask what he wants to eat he says "Whatever" I tell him "I am all out of Whatever" I get so tired of fighting over what to fix him and tonight he says just forget it. We have been married 39 years and I am tired of trying for figure out his meals. He is old fashioned and believes I should cook for him and this is going to start WW III. I am at my wits end. He usually ends up saying a gl of milk and some toast! He is not well to start with but I don't like serving a gl of milk and toast for his dinner. It's always my fault that he goes without or won't eat what I make. Today I had to be out most of the day so I put a pork loin in the crock pot with seasonings and he looked at it and said "I am not eating that." It was good by the way. So I made him mac and cheese which he says he is burned out on but he ate it. Then we had a fight again about foods. He just says FORGET IT! and stormed off to bed. He won't even help me figure out what to feed him. He says he has already done that. I have had it, I quit!
