Fuck knows what’s going on in this family, it sounds like a horrible mess whatever had happened.
The parents could genuinely have been/be deeply worried about their child’s connection with this person and feel that they have been groomed/exploited/abused. The child/now adult could genuinely feel this isn’t the case and they’re fine etc
It’s not impossible that both things are true.
Parents can freak out and misunderstand situations but kids and adults can also not realise/understand they are being mistreated in some way.
Now it sounds like the parents might have really fucked this up by going to The Sun which was never going to go well but it could have been a real but misguided attempt to get some help.
Maybe not, who knows.
Whatever has happened, this is a monumental car crash.
