Um. Yeah. Am completely serious, and be sure to mention to the cops you fear for your safety. If your scared of him not having to leave at that time, then go to the nearest police station and tell them everything so he doesn't know until it's too late and he has to leave. And for Pete's sake be very detailed with the things he has done to you and your mom.
I'm sorry to hear this. Unfortunately if he has threatened violence he may go through with it. Verbal and emotional abuse are also very serious, if not illegal. Have you tried talking to your mum about leaving him? I'd guess she is scared too. I have been in an abusive relationship and it's not easy to leave. You can go to the police but I wouldn't guarantee they can help. Be safe. Do you have other family?
They'll arrest someone. Never can be sure who
theyll find some reason to fine or arrest someone for something
i don't think so but if he started getting violence then call the cops
