Caring for a Strong-Willed, Controlling Spouse - How do you do it?

The tables have turned. I'm a Lymphoma survivor of nine plus years. My wife has taken great care of me. I have a positive reaction to Ibrutinib and have been doing well. Now it is my turn to care for my wife. She is scheduled for surgery to get a firbroid removed from near her Ovaries. We won't know whether or not she has cancer until after the pathology is done, two weeks after the surgery. She has to have a complete hysterectomy and maybe even lymph nodes if there is cancer. At any rate for a month or so she will be healing. Here surgery is scheduled for the 26th of April. Her surgery was going to be on the twelfth but she caught a bad cough and has to get over a viral infection first. She has seen our family physician twice, and is just now slowing down on serious coughing and eating again. I do my best to cook, clean house, shop, and all the things she insisted on doing by herself. She is very exacting on how she wants things done. I am hard of hearing and she gets upset when she has to repeat herself. If I guess at what she wants and get it wrong, oh well, you get the picture. I have to control myself better and be there for her. I have to swallow my pride and do what is right for her. It is not easy. I will enjoy reading further at how forum members cope and provide the care their loved ones deserve.
