This is a very long story so I'll try not to write too much but there's so much background to go into first. Long time poster but I've obviously name changed for this.
Also possible TW as I am going to mention paedophiles etc. sorry not sure how best to put it.
Growing up my parents were emotionally abusive - it has taken a long time to realise this and even now I'm still remembering things/going back over things and realising how awful they were and how badly I was treated. I have other siblings but I was definitely the scapegoat of the family, never given the same opportunities, never allowed to do as much as them etc. often pitted against siblings and could never do anything right or be good enough. It's only since having my own children I've realised how horrible my parents were to me and often cruel.
As a teenager I was constantly belittled, told to find somewhere else to live but then told I wasn't allowed to leave if I tried. My parents stopped me from going to university in another city saying I couldn't afford it etc then made me get a job and work my arse off and constantly told me to find somewhere else to live etc, I was never allowed to go out without permission or allowed a social life/friends to visit and ultimately my studies suffered as a result with me also ending up as an inpatient in a psychiatric ward and having to postpone my studies because of this. So it was constantly being told to do one thing then when I did it, I was in trouble for it or in trouble for something else.
My older half sibling I never got on with, they were always treated differently by my mother and heavily favourited. Over the years some awful things happened like them trying to push into the bathroom when I was undressed in there and me having to scream for help and then nobody believing me. At one point I became so concerned I checked their laptop when they were out and they had been looking at some really dodgy stuff - young girls etc online. I told my parents but they brushed it off and acted like it was fine - even said they had looked themselves and there was nothing etc. after this I had to have a bolt on my bedroom door because they would loiter outside my bedroom and peer in if the door was slightly ajar, I became frightened they would come into my room etc so I needed a lock.
Fast forward some years, I've moved out etc and my parents always expected me to call every single day, be available for visits on short notice, still tried to rule my life by constantly asking where I was going/who with/telling them when I was back home even when I didn't live with them etc. and I foolishly thought this was normal and enabled it and allowed it to continue although there have been many many times over the last few years when I have considered going no contact or low contact but been so frightened of any repercussions that I just caved in the end and let it carry on.
After having my own DC, they very much forced this older sibling on me saying I couldn't cut them out and they had to be involved with DC etc which I tried to avoid but ultimately allowed some visits etc to keep the peace as the reactions if I didn't were horrible.
A few months back, my other sibling told me they had concerns of their own and accessed the older sibling's tablet some years ago. That time, they found nude photos of young children (they described them as screenshots of nudist families etc with the children specifically cropped and saved if that makes sense) but obviously years had passed and nothing had been said/done as they knew our parents wouldn't believe them or take it seriously. Well I told my parents and they reacted much better than I had expected initially. They said they would cut contact with the older sibling, this was wrong, they couldn't believe that my younger sibling had kept it to themselves etc etc. obviously we had no actual evidence of this as so much time had passed but I wanted to go to the police but was stupidly talked out of it.
Anyway fast forward to last week and I found out my parents have been having contact with older sibling, arranging visits etc. Now my parents sometimes have my DC for an afternoon every now and again and come and visit us etc. so as soon as I found out they'd had contact with the older sibling I said I could not continue a relationship with them or allow my child to.
Well, I'm the fucking devil now. They said they have no intention of stopping contact with the sibling, that they are not answerable to me, that I'm bang out of order for bringing it up etc etc and that I'm being cut out of the will.
So naturally I've blocked them all and will be having no more contact. What the fuck do I do now with regards to the other stuff?!
I have no evidence that the sibling had these images, if I contact the police etc and nothing is found what would happen?
Sorry this is extremely long and if anyone has read thank you.
Trying not to drip feed and get everything in but there's just so so much it's impossible.
