Growing up as the child of a mother who had an affair with a married man: When I was 14, mum handed me a letter to open when she died. Decades later she killed herself. Her heart-breaking message to me: 'Find the love I never did'

Just before bed one night, when I was eight, my mum told me she had a new boyfriend. She seemed lighter than usual, excited even. But then she told me that Graham was married.
