I had a 27 year old boyfriend in the 90s when I was 17. He was an ice cream van driver *shudder*. In fairness my mum absolutely didn't accept it. She went totally off the deep end. She called the police who gently explained that as I was 17, it wasn't a police matter, then she sent my former squaddie uncle around to threaten to break his legs.It’s amazing what was acceptable in the 90’s. When I had my first job at 16 in about 1998 I had a work colleague the same age as me who was in a relationship with a 42 year old. She’d met him when he was her school bus driver. We became quite good friends and I remember meeting him for the first time and he was so repulsive, balding, overweight just awful. I knew it was icky but not one else cared. Her family didn’t seem to mind either.
To this day I don't really believe he was predatory though. His problem was failure to launch. He was an immature idiot and I would have outgrown him within a year.
