Hello, I am hoping for some advice....
Many years ago when was 13/14 I was staying with my divorced father and he assaulted me in the middle of the night, he said he was confused/sleepwalking. My mum knows but my sister does not as I did not want to wreck her relationship with him. So now my sister has a young daughter and I think I should quietly say something. I asked my mum but she would not give advice, I cannot push it because she was treated very badly by him. This will cause a lot of angst.....please help.
