I recently took my wife away for a week in a rented cottage the countryside' overall we had a good time and created some special memories. One evening we were sitting in the garden and she looked at me and asked who i was and what relation i was to her, now i knew this was going to happen at some point but nothing prepares you for the shock. Once i had recovered and explained that we were married she seemed quite shocked and asked me where i had been for the last few years. I must explain at this point that we have been together almost every day for the last 38yrs. This conversation has now taken place on a daily basis since and i feel a growing sense of despair. Is this typical behaviour and how should i react? Any advice would be gratefully received.
