My husband’s father has had to move into an in-law apartment in our basement. He has Type 2 diabetes and financial issues. My biggest issue is that he is of sound mind but he doesn’t listen to what doctors and I tell him. He is continually eating sugar and when I try to talk with him about it or make a comment he tells me that his doctor said it’s ok for a treat every once in a while. He has even told me “if you’d take the time to do the research you’d understand.” I had gestational diabetes with my daughter that I controlled with diet, so I do understand. Either I continue to argue with him which makes everyone in the house miserable. Or I let him eat sugar and keep my mouth shut, but then I feel like I’m being a bad Christian that I’m allowing him to eat himself to death. He also is supposed to use a CPAP machine but continually makes excuses as to why he won’t. Same issue. What are your thoughts?
