I am 28. My father refuses to come to terms with the fact that i am no longer living under his wings and due to get married soon. Based on the following scenario what do you think I should do ?

I think he is going in sane.

Is it dementia? He is 72.

Someone from the government census passed by his house to ask him who lives there.

He said that he and his daughter live there.

I live in a foreign country and have been for the past 5 years.

I visit him once a year.

He tries to argue with me that as long as I am not married my residence is where he lives .

That the apartment I am living in now is not my residence but just a diggs?

What does this mean? It is really weird. I am convinced he is suffering from dementia.

Opinions please.
