When I was 11/12 my mother had an affair with my father’s best friend. I’m the only person in the family who knows. Two decades later I am still finding it hard to forgive her. We have never really talked about it or discussed it. She would take me with her to his house and disappear upstairs while I watched cartoons downstairs. Sometimes I wasn’t sent to school and we’d go round. She also let him kiss me on the mouth once, and would kiss him when my father was around. This has had a terrible effect on me and I find it hard to get over it.
