My 90yr old mother is staring to need more help with day to day chores. My parents still live together in a large home that is not very safe. My mom is okay with someone coming in but dad is resistant to having outside help. He is a very stubborn and angry old man. He tries to do all the home repairs and most of the cooking. This is too hard on him but he thinks he is fine. He treats my mom as if she is an idiot and should be able to do things herself. He then yells at my mom when she asks him for help. Mom has a house cleaner and a gardener. I spend one day a week helping out with taking her to Dr's appointments, shopping and other tasks she might need. I cannot give up more time than this. I wonder how to go about hiring someone to help her without him getting angry.
