My 92 year old mom with dementia was recently hospitalized for two weeks, then lived with us for a month before being placed into a memory care assisted living. She can no longer live alone safely. She is adjusting slowly to her new place, but she continues to ask to go to her home which she lived in for 65 years. She hasn't been there now for about six weeks. We will be selling the house within the next few months so it already looks different than it did when she lived there. It breaks my heart that she will never return there or live there again. I know it is best NOT to take her there again, but wondering what others have done in their situation.
"I know it is best NOT to take her there again, but wondering what others have done in their situation."
In my humble opinion you just answered your own question.
When she is more adjusted to her situation help her make a scrapbook of memories around this home.
I think it is clear from what she is saying that she is not saying "Can we walk through one more time so I can say goodbye", (for to ME, our homes are almost sentient beings). What she is saying is she wants to go home. And that can't happen.
It's heartbreaking, isn't it. And it is worth grieving, so allow her that and be honest with her.
