Father has early dementia and confuses his medications, he doesn't eat more than sandwiches and sulks in his room if we don't agree with his choice of girlfriend. His "girl friend" is a well known hooker. we have had contact with the police a couple of times but now he wants to spend the weekends' with her in 'her hotel'.
Someone has convinced him to get a one bedroom apartment which he anounced today that he will be moving into on Aug. 1/14.. H
A person with dementia, even mild dementia, should not be living alone. But if he is not incompetent in the legal sense I don't think you can stop him from trying. I hope the lease is not very long-term!
Begin his independence now. Stop waiting on him in any way. No laundry, no bedding changes, no sandwich making -- let him practice being on his own. Tell him you disagree with his choices but that you respect his right to make them. (That in itself might take some of the fun out of this adventure.) If he wants to move and can arrange it all on his own, including the physical moving of his furniture, etc., well, you wish him well.
Be prepared to take him back in when the fun wears off or his dementia worsens. Love him. But realize you can't control his life.
Maybe long before August he'll some to his senses. We can only hope.
