My husband is 87 and I'm 69. He keeps seeing more than one of me, but it's only while I'm home. He keeps asking me about all the other girls. How do I handle this. He sometimes gets very angry when he sees me as me and wants to know where I've been and how could I let these other girls in the house.
This is really a tough situation though as sometimes there just isn't anything that can be done. My mother had some experiences like that, long before I knew anything about how to address it.
Once when she was staying with me while my father was away, a friend came over and brought some food which Mom loved. She was ecstatic, and excitedly greeted the woman, asking her "are you my daughter?" it was kind of like a sucker punch for me as I hadn't realized the extent to which she sometimes became confused.
And once when my brother came home from out of state to visit, she asked him if he was her son or her husband. At least she was cheerful and excited to see him.
These were years ago and there wasn't as much publicity or information on dealing with these kinds of confusion issues.
Try to get to the root of his anger; is he feeling confused by all the "new people", afraid you have left him, does he resent that he has (imagined) sitters because he feels fine?
