My mom's boyfriend slapped in the face and called me a whore because my mom tried to get me arrested because I snuck out, is that child abuse?

He has no right to touch you. While you should not be sneaking out, bad things can happen to teens out past curfews, nothing excuses what he did. You can report the incident to Child Protective Services. Now here is the problem with that. When you do that, it will really put your mom in a bind because now her boyfriend won't be able to come around anymore. Whatever your differences with your mom, this will strain your relationship with her; if you report the incident, do you have other family who will take you in? You do not want to be out on the street homeless, that life will destroy your life before you even begin living. You need to start with an adult conversation with your mom- I love you and was wrong to sneak out but he had no right to touch me. He hurt me and that is not right. You are my mother, you have to protect me. I will not allow him to touch me again. This is VERY real stuff and your personal safety is at stake. You can and probably should report the attack but you better have a plan before you file the police report. Best of luck to you and stay in school.
