One I know of....elder...wife suddenly passed in her sleep. He was in early 60's I think.... He latched onto a young woman in her late 20's...divorced with a child. His words and I quote " when your old dog dies, what do you do? You get a nice new puppy". I was appalled. This was maybe 6 months after the death.....
Two others I know of wasted no time either. One around 80 snapped up a 60ish year old sister who had been taking care of his ailing wife. They "dated" with a chaperone. How sad is that!!
I was widowed awhile ago and the last thing I want is to remarry. I had the best possible man for me and my marriage to him is forever.
