Nobody should endure domestic violence, and if you feel that you or your children are in any immediate danger then your first priority should be to call the police. In order to ensure that you are not subject to domestic violence in the future you can apply to the courts for a non-molestation order which will prevent your partner or ex-partner from harming you or threatening you with harm.
I’ve never heard of Edward Furlong, but he doesn’t sound like a very nice chap. Having been charged with battery twice at the end of last year he has been arrested again for allegedly attacking his girlfriend. He’s also been sued by a previous girlfriend for ‘assault’ and has been banned from spending time alone with his six-year-old son. If I weren’t already very unlikely to watch his films I’d now make a point of boycotting them.
