A couple of years ago my sister found inappropriate pictures of minors in my dad's gallery on his phone. There were pictures of children in third world countries all lying together on the concrete floor with barely any clothes on, children in bikinis and a child in a nappy with their legs spread open. My sister was really upset and showed me and my mum. I had a look through his phone and it seemed these pictures had been saved from Pinterest. He had searched on Pinterest for things like 'barefoot kids', 'kids swimwear' ect. Also in the past I walked into the living room and he had toddlers and tiaras paused on the tv. I confronted my dad about it and he went crazy, accused me of calling him a pedophile, theatened to push me down the stairs and kill me but insisted it was all a mistake.
My father had always been abusive growing up but more mentally and occasionally physical never sexual though. Social services never helped us, I have however had councilling and CBT to help deal with my childhood.
He was very abusive to my mum who has agrophobia and locks herself in her room most of the time. She will not leave him though. My mum at the time of finding the photos was in touch with someone from rise, she told them about the photos and they called the police. The police came round for a welfare check and asked about the photos but said they could not do anything because they were not extreme enough.
We all sort of just forgot about the pictures and tried to move on. However a few weeks ago we went bowling and I saw him staring at groups of children and yesterday I caught him looking at this scrap book from a primary school he had found at the market. It had lots of pictures of primary school children in, and there was one with the children in swimwear. He said he wanted to sell it on ebay, as someone who went to that school might want to buy it. Its all just really messing with me, I feel so upset and angry, I feel its ruining my life. I am still worried he is looking at pictures but in a way I don't want to know so I don't try to look. Also I don't want to tell my partner incase he judges me.
I just don't know what to do about it, it seems it's not bad enough to get to police involved again. I am supposed to be moving in with my partner next month but I feel bad for leaving my mum and sister with him. Please could someone give me some advice on what to do.
Thank you
