I have this adult sister who has literally terrorized the family since she was at least 11. She got heavily into drugs, which included stealing everything that wasn't nailed down. She is now 31 and still lives at home, bore a child and her low life b/f lives with my parents. The b/f refuses to work and lays in bed all day while my mom raises the baby. My sister is violent,abusive and a true narcasistic BITCH! My parents won't throw them out for fear that my nephew will suffer the consequences. When me and my siblings intervene, my mom tells me to stay out of it. My dad wants the b/f gone as they beat each other up every other week. My nephew can't say many words, but he can sure say "fuck" a hell of a lot. I want to call Dyfus on them so bad but fear that in her vinditive ways, she will lie and not allow my parents to have him. What to do? I wish I could get her arrested as she is on probation, but then the dad will get him. The b/f has a child that he denies is his yet refuses to take a paternity test. I have tried reasoning with them without success. She hates my guts. I roamed the streets years ago when she was knee deep in heavy drugs and got her temporarily clean. My nephew was born addicted to methadone. Just a horrible situation that greatly saddens me. Any suggestions?
