My younger brother who is 16 is dating an 18 year old girl and my mother hates her my mom wants to know if there is anything she can do to get her in trouble for having sex with my brother. She has no proof except the word from me and close friends. He has run away and wont return calls, this girl has kept him from going to school and is ruining his life. Is there any way we can take care of this? Someone please help.
