Sending you a big hug, @bclane !

My husband and I care for my mother-in-law. Little by little she started not recognizing us, but, as in the case of your husband, she does not question who that strange man and that strange woman are doing in her apartment. She seems to take for granted that she needs help, even when she sometimes refuses to collaborate to stand up or sit down, and that these two people are there for that.
