TPR had fallen into the habit of shaming me in public. For example, he made lewd remarks about his choice of life-partner to our widowed bed and breakfast host. Then I caught him laying bets on the outcome of Wimbledon 2017 with my old colleague MM.

When I said to him ‘The headmistress will see you in the study’, he knew that he was in trouble.

I also vowed to take more interest in our joint finances when we returned home.
