This is something I’ve genuinely had to go through with one of my girls. I supported her as much as I could at that time and our relationship as Daddy was scrutinised by the therapist.
I felt I was being examined as much as she was and I swear they suspected that our “co-dependent fantasy fetish” was half the problem and I feel they tried to separate us.
It wasn’t pleasant, but I carried on for the girls sake. She needed my support and the only reason she attended the sessions was if she knew I was there for her.
