My wife is obsessed by the idea of strangers entering the house and stealing her possessions. In reality, she is hiding things and forgetting where they were put, although they always turn up - sometimes weeks later. She is constantly engaging in searching for things, even though she cannot always describe to the ability of my understanding what she is actually looking for She has created hiding places which have totally baffled me for even quite large items. She is convinced strangers have keys to the house, and continually claims I have friends who come in after she has gone to bed. My problem lies in the dilemma of denying her fantasy about stuff being stolen by strangers , and thereby provoking anger and great distress, or agreeing with her for the sake of peace and quiet, and thus reinforcing the idea that is actually happening. I do not doubt other care have the samesort of problem. How do they cope?
