My 83 year old wife of 62 years has Alzheimer's and is in a wonderful memory care facility. She constantly asks me to stay and sleep with her (which is not allowed) and hates it when I leave her at the end of my visit. I have to make up "therapeutic lies" or just leave without telling her. In either case I feel guilty and wish there were a way I could help her to understand that we live apart because she needs more care than I can provide ( I tried for several years and even enlisted a home care provider). What does anyone recommend to handle this situation?

If your wife still knows you and expresses that she wants you to stay, it sounds like she may not be so far gone. A different kind of facility may be right for both of you.
Good luck.
