My elderly father, who was in early dementia when he met this gal at his retirement apartment, proposed to her within two months of meeting. He then introduced her to our family and everyone had red flags! We all tried to talk to him, he didn't listen and they ended up getting married within six months of meeting. At first he seemed happy, now, as his dementia has progressed he has turned very quiet and watches TV or movies most days, which is fine. This past summer as I was thinking about why she never talked about her family or past, I got very curious and started looking at ancestry.com and low and behold, NINE other marriage surfaced!!! She had told my father and I she had been married twice before (divorced twice), which I am now thinking is a copy of how many times my father has been married, which is twice, though both my mother and his second wife have passed. She has become more and more short with me when I call to talk to my father as well as stopped being home when I come to pick him up for our bi-weekly lunch dates. I know my father wouldn't remember if I told him or even showed him all the marriages, but with her blocking me from seeing my dad, I am not sure I have a choice but to confront her about her deception. Thoughts?
