Oh honey please listen to me. As a mother I can tell you that there is NO threat he could do to your mom that would make her scared of him and not protect you. Your mother would want to know, so she can put an end to it immediately. Go to school, tell your teacher and they will call your mother to your school, you can get the police to pick him up witout you or your mother even seeing him. I'm sure the.next stop will be the hospital to make sure you are ok. Do not let this monster continue abusing you, your mom will not want that either. I'll be praying for you.
