@wctdoc1943 How very sad.....but you sound like my kinda guy; involved, vigilant, caring, unswerving in your loyalty to her and to your relationship, and willing to do the heavy lifting when needs be. Good for you!

I'm sorta there with my wife. She depends a lot on me due to her various conditions, not least of which are two recent falls, one resulting in a broken wrist, the second three days ago where she broke her humerus....and nothing humerous about it...at all. Fortunately, she has been 'good' lately, engaged, energetic, not quite so beset as in the past two years with aches and pains. But she does know to come to me for unusual events on line where she feels she needs to act, or is being pressed to. My oft-repeated rule for her is to tell the caller that she will call the purported institution/amazon/whateveritis directly herself, and to promptly hang up. No use in extending the conversation, and she knows to end it immediately that way. Had to run over to my dad's place ten years ago the same afternoon I had migrated his laptop to Win10. He got a scam call from 'Microsoft Services' saying they noticed he had a virus. He had actually already given them remote access when he called. I'm a long distance runner, and I literally ran all the way to his place a few blocks away. He had hung up per my instructions, and force-stopped his laptop. They called just as I entered their apartment. Told them to buzz off, and to not call again. Ran a malwarebytes scan just in case and his computer was squeaky clean. Whew!
