Hello and welcome @weebiscuit I’m so sorry to hear that your husband has bladder cancer, is there any talk of surgery or has he finished treatment? Sounds like feeding him is a real problem for you. If he’ll drink the Boost or Ensure, that’s a real plus. You can try freezing some of it to make ice cream!
You are doing your best and you don’t want it to become a big issue between you. He knows he needs to eat and he will. Does he have another doctor visit soon? Maybe they can explain the importance of eating especially after chemo.
Your statement , he believes “this is what it’s going to be like for the rest of his life.” You make him sounds as though he’s very depressed. Do you think he’s depressed?
