These are very trying times. How appropriate. I have the same situation and sometimes I feel sorry for myself. I have been caregiving on and off 8 years. He is still active and can do things but he has had surgeries and recently a fall with fractured pelvis meaning more work. But his short term memory is awful. He was supposed to see a neurologist but then said there was nothing wrong with him. His memory is fine. Yes it is because I am answering the same questions over and over and it is on appointments current things and I took find that now have to be at all appointments because he comes away with things not quite right or how he wants to hear them. It would certainly be helpful to me if he would acknowledge it and get whatever help is available or know it so work on it. If I start getting annoyed, he expresses his unhappiness.
I get out and play cardsm mahjong, see my friends, go to the gym (this helps a lot) and keep to my routine or I will go nuts. It surely takes an enormous amount of patience. One other thing we are thinking about is that we too, the wife, are aging and thinking about the remaining period of our life when we might have other ideas on how we manage that - such as I would like to have been in a smaller house before now and he won’t do it. I sometimes complain to myself or my group - what about my life. I feel like his emergency contact and personal assistant. Keep your friends close. We all need each other.
