Child abuse a secret

I was molested as a child by my father. He was very drunk and it was only 2 seconds then I said Dad I'm tired. He looked shocked as if he didn't know it was me. After the incident he fell into a deep depression and has been seeing a psychiatrist since. I learned to handle it in my own way as I felt it was accidental and not really forced or violent. I have a boyfriend who I love very much, I sometimes feel obliged to tell him, but other times I feel that telling him might blow the incident out of proportion and change the family relationship for the worse. Do I need to tell him?

No! There is a risk that telling your boyfriend would affect your sex life in a negative way. I have met many patients who destroyed their present sex life by being too open about former sex experiences.
