My husband does the exact same thing! He thinks going places would be fun, but he never wants to when the time comes. He is happiest at home,

If anyone is going to insist that i go somewhere that i have decided i do not want to go you are going to have a fight on your hands! Just because I have Alzheimer's does not mean I have lost my autonomy. I realize down the road when I deteriorate further, circumstances will have changed. But until then both parties will have to be as accommodating as possible. When the more powerful party (the caregiver) takes the attitude of "insisting" you are going to get resistance every time. In these early stages we are not "gone" yet.

I find that hubby does not give me an answer when I ask him if he wants to do something. I think we have to remember that when we say - lets go see ______, there is a good chance that they do not know who or what that is and so they would just as soon not be stressed. I had to almost force hubby into the car today to go see his brother - he did fine and had a good time but he would not go in the house for his brother (don't think he knew him) Finally, I went back out and then he came in - I must have been more familiar today than his brother.

Yes I had this experience also. I feel it is withdral and they are often aware of the cognitive deficits and they are embarrassed. Social isolation is not good for anyone. If she hasn’t got a legitimate reason it’s ok to insist she go and maybe you can sit in the back and observe to gain better insight. You are doing a great job.
It is a noble thing you do. 😇

I don't know if you are expecting too much, but I think she is expecting too much. I find myself that I overschedule my life. I am trying to do more than I am now capable of doing. I don't know if it's symptomatic of ALZ or just getting older. I even put more, literly, on my plate to eat, than my appetite can sustain. It has taken me a while to realize that this may be my new normal. You might gently suggest to her that too much may just be too much. Good luck.
