I hit my moms boyfriend and she doesn't appreciate it
Well I'll start by saying I'm 16. Not to brag, but, I am a pretty big kid. I'm 5'8" with quite a bit of toned muscle. I was downstairs and I overheard my mom arguing with her boyfriend of 2 years. I don't know why they were arguing but I overheard a smack. I ran up stairs and saw him grabbing my mom and pushing her around. I ran over to him and punched him in the face. I started yelling at him telling him he better never touch my mom again. I starting swinging on him and my mom pulled me off and started hitting me and yelling at me that I can't touch her boyfriend. I was so angry. I went down to my room after she stopped hitting me and I tore up my door and walls. I punched holes in them and I was out of control. I was just really upset. Anyways, she is very upset that I interfered and doesn't want to listen to me when I tell her what a scumbag her boyfriend is. She won't end it with him but things are getting worse. He is getting louder and more aggressive with her and I fear I'm going to lose control one day and beat him so badly and get into trouble I need her to leave him before it gets even worse but she won't listen to me. What can I do to help her see he is a scumbag?
