Carla, look at what you have said:
"TBH, he's not the sort for physical abuse, but it frightened me enough to want to call them."
From everything else he has said, he is the sort for physical abuse - if a man has done it once, he will do it again - and he has done it more than once already. By inaction you have shown that you find it acceptable. S
hocking remark this is it is the bare-faced truth: right now, you are a part of the problem.
Right now, you can be a part of the solution. Act on what everyone else here has said.
I have never said this to anyone but one of the earliest memories of my childhood was my parents fighting. Really, now I know that my mum was being slapped about. I slept in a crib in their room, that is how young I was. I even remember exact words she was saying and how my dad was poo-poohing her desperation. I was shaking with fear and frightened that if they ever discovered I was awake that I would be in trouble.
My dad left when I was seven and a month before he left he beat the crap out of my mum - my older brother, sister, and I were wide awake and I remember feeling desperate and my older sister hysterical.
