We’re dealing with the same thing ourselves. Unfortunately, this is a long-term companion of my MIL (30+ years). Never married, so we have no say at all in his care (not that we’d have any say anyway, unless he was a blood relative). The (blood) family doesn’t want to deal with it so is in denial…leaving him to live by himself when he is deep in the throes of dementia or Alzheimer’s. Everybody is in denial, and he’s driving around on L.A. freeways getting lost on an almost daily basis. We’ve offered to take him in, but his family in L.A. won’t let us. This is such a sucky position for any family to be in. 🙁
My heart goes out to everyone who has to deal with this.
