I worked out that my DF was a drug dealer by the time I was 10, class B. I didn’t tell my parents I knew as they probably thought they were protecting me by letting my grow up or knowing.
When I was 13 my DF starting working with someone who was related to my friend at school. She knew what her relative did, so grilled me to find out if I knew. I admitted I did and my best friend at the time heard, went home and told her mum: her mum is friends with mine so she already knew. But told my DM I knew. From then on it was just open that my DF was a drug dealer.
By the time i was 15, my DF (high up the chain, not a street dealer) had moved on to class A, and had started smoking it himself. He gave my mum a black eye and she left him. She had nowhere to go so she left me with him.
By 16, he’d been ripped off in a drug deal, hadn’t checked the money was all there and was short £10,000s. He decided at that point he needed out, he owed people higher than him he had no money to cover what he’d lost so he told my mum, come get DD, and he left. With a huge debt and a price on his head. Luckily they never did anything to me and my mum but we were followed for weeks, maybe to see if we led them to him.
That was a traumatic childhood, constantly on edge, I was there when the house got raided, a girl at schools dad went to prison who he was associated with, I was terrified all the time that he would go to. He wouldn’t have got 9 months he’d have got 14 years.
So to the people saying she shouldn’t stop her DD seeing him, you need to consider the safety of your children. As someone who grew up like that I can promise you, I would have wanted to see my DF too, but I would probably have had a much safer and happier childhood had I been removed from that environment. Also it’s insidious having to lie to your parents to protect your other parent. Her GP are well out of order for encouraging her DD to lie
