this will be long so just hang with me.....My twin sister( we are both 16, sophmores) is dating the guy from hell. Just some background info on him: He is a junior, he is fairly popular at school, i think he might abuse cough medicine and other drugs, my sister said he drank himself to sleep everynight when they went with friends on a camping trip. He also demands that my sister pay for everything because he thinks that we're " rich", he is also a racist and talks about joining the KKK. tuesday, my sister was wearing a bikini and i noticed big black marks, about the size of a belt buckle across her back and I asked her if it was him, she started crying and said yes, i didn't tell my parents (yet) because my sister begged me not too, she said she is ashamed and can't tell them yet. I am very pissed and plan on talking to my uncle ( who works for the state police), am i doing the right thing, i don't want to betray her trust, but somebody needs to know....
