One of my DPs has become obsessed with conspiracy theories. They don't talk to me about them unless they are a bit disinhibited by drink. I don't deal with it well. It has been going on for at least a decade and the beliefs have become progressively more extreme and deranged - and wide ranging.
I am looking for advice on how to bring them back to reality from those who have been in a similar situation - what helps and what doesn't? They are in their 70s with noone else in the family sharing these beliefs, including their DP.
