Since we got back from our trip, my mom has been messaging how lonely she is.

While we were gone on our trip, she told grand daughter how lonely she is.
She stubbornly refuses assisted living because she has this crazy idea that once she is there, everyone will forget about her and no one will come to visit.
It’s also about control. She would be giving up some of that.
She makes up lies about the facility.
So when she texts she is lonely I want to respond by asking her “what can you do about your loneliness “?
I don’t want to hear she is lonely. She has brought that on herself.
When home care was coming, she at least had social contact, but she cancelled home care.
How to respond, so that these texts stop coming? Or just keep ignoring them?
