My FIL is 90 years old. He has declining health. His wife (second marriage- first wife of 50 years deceased) has dementia. She has been diagnosed with Alzheimer's, but I think the Doctor just threw some pills at her, and never gave her a thorough evaluation. The step-family situation is another piece that makes this situation hard to manage. For whatever reason, my FIL will not tell his wife "no" when she is making poor decisions. Some examples are: giving him supplements off the internet, rearranging his pill box, giving him orange juice when blood sugar high, home canning done incorrectly, driving without a license, inappropriate charges on credit card, etc. Do you have any ideas why my father-in-law will not stand up to her. These are some ideas that we are considering- 1. My FIL also has dementia that we are unable to see/admit 2. My FIL is in denial and is unable to see her lapses in judgment 3. He is of the older generation, and is a true gentleman. He does not want to hurt her feelings 4. All of the above Thank you for any insight.
