I assume that was written by a secondary account from someone here. It seems to be a common way around the HN demands for civility... :-(
Regarding the victim, my guess would be on early stages of dementia and/or emotional trauma after becoming a widow.
But if I would discuss this with a victim, I would try bringing up the psychology of a scammer. First in general terms, like the Nigeria letters, then the specifics about romance.
To really hurt someone this bad is not far from the level physical torture. It is not easy for normal people to live with the self image of destroying an innocent person's life in that way. So the perpetrators of such horrible acts have to despise and blame the victim. (This is what scare me about hateful political idealists, by the way, they tend to think people contradicting them are evil. Not an American, so this was not about the election.)
So scammers and criminals really hate and despise the victim.
(This scammer wasn't someone desperate or really poor, that is partly another discussion.)
Which gets me back to the what I comment on -- "hilop" could probably get a career in scamming, he has the right attitude to other people.
