I don’t think it is a posibility to contact them unfortunately now, and I only know of the control side of the abuse for the other 2 and not any violence, although it may have happened. He started dating a girl my (detail removed by Moderator) knows and I heard from her she left him due to severe attempts to control her and very nasty behaviour.
I am just feeling angry that I didn’t see it for what it was at the time. It was a serious thing and due to me being used to forms of aggression and verbal/emotional abuse I let it go and just made a plan to leave him. I wish now I had called the police and kept the messages. I think this can be a lesson for anyone else, it is worth reporting if you have been hit and are suffering abuse. It’s not a trivial matter. It starts with the control and slowly over time gets worse to reach violence when you say no. It could have been a lot worse for me if i’d let it go on after the first time.
