My in laws are both 93 and live about 4 hours away from us. My sister in law has a second home about 30 minutes from us. We recently placed my mother in law in a dementia facility near us with the thought that my father in law could spend time between the two homes here and his own home. After spending the month from Thanksgiving to Christmas with us because of poor weather, he now thinks that he can move in with us permanently. We get along great, but I don't want him moving in. I feel as though my marriage and mental health will suffer. While he was here I felt as though I had gained a second husband. Someone else to do laundry for and cook for and to clean up after. I don't mind him visiting, but don't want him moving in. As a side note, my husband is very non confrontational and will never tell his dad he can't live here. Help!!
