HI sweetie
Sending u massive hug out, I know exactly how emotionally draining and horrible it feels to have to call police on your own son , its like we r with the abuser again, I Too sadly have to do this sometimes, please get support for yourself, not sure how old your child is but I would recommend getting the youth offending service involved to help work with your son. I am currently doing this, has your son tried counselling, is there any male role model that could have word with him, you have to work so hard with these kids to get them to see they are mirroring their dad behaviour. Feel free to private message me if u need to chat further. I will say always try to protect yourself and your other children, don’t feel bad about having to call the police. If there is one thing ive learnt , its better to call them now at first incident then let them think u r too scared and wont, hope police got to u in time
