Hello! I have a question that's not relevant but I need help with advice. I can't find a place for myself... Maybe among you there are lawyers who know the law. My husband and I separated because he is a police officer and threatens to take the child away. Can something be rewritten? Any criminal cases? He writes threats saying I will beg him to show me the video of the child. Inside it's so restless... He himself is very tough, on this background we separated. Now inside there is anxiety... I can't find a place for myself
