I think it’s appalling but my 80 yo mother seems blind to the situation. Even though she saw how he received DWIs and neglected my daughter and their baby. I refuse to be around him and my sister but my mother is going along with it. I think perhaps she’s not taking her medications or needs checked for dementia. Should I contact my mother’s doctor?
My sister dated a man 20 years her senior while they were each married to other people. They divorced their respective spouses and married. Her new hubby tried to extort hundreds of thousands of dollars from his ex (who was 20 years HIS senior). It was a horrible, messy and painful process. New hubby was a real jerk--but mother insisted we all be super nice to him and make him feel welcome. I've never been rude to him, but I sure haven't been trusting or warm towards him. (There is far, far more to this backstory, but you get the gist).
Mother ADORES this loser. Good, somebody should, I guess. And yes, mother encouraged this affair, unbelievably---b/c sis said she was "so unhappy" in her marriage at the time.
I just don't ever see this guy. I also never talk about him with mother. That's the best I think can be hoped for.
Now if SHE were marrying the bum you might have a case. And if Mother set them up and encouraged them, that might be questionable.
By all means, don't be around them. But surely Mother gets to make her own decisions!
