Dementia and romance.
My husband and I recently moved my 82-year-old mom with moderate dementia in with us; she could no longer manage assisted living, but is not ready for a nursing home. While she was in AL, however, she was constantly talking about one man or another, sounding very adolescent. One of the men (who does not have dementia) paid attention to her for a bit, then transferred his attentions to another lady, making my mother very angry. He then had to move out, and we thought that was the end of it. Since she moved in with us, though, he has been calling her and now they want us to take them out. I'm very torn. She is an adult and his attention seems to make her happy, but I question how "real" the attachment can be for someone whose memory and logic is so impaired. And why would someone who is not impaired choose to have a relationship with someone who is.
My mother also only wants to watch movies and tv shows that contain a lot of romance/sexual situations.
I will add that since my father died at a relatively young age (51), my mother has a history of making bad choices in men, even marrying someone at the age of 70 who she was convinced was "a good man", who proceeded to take advantage of her financially, abuse her verbally, and attempt to separate her from her children. They divorced after 3 years.
One more thing: we are barely getting started caring for my mother, and I can say unequivocally that this is the most stressful, complicated, and exhausting time that we've ever experienced. I don't know how people do this for years.
