You say you don't want to get your abuser in trouble. How many more times do you want this to happen? Are there others they are abusing? If you don't stop the cycle it will continue until someone does. How are you going to feel if they abuse one of your siblings or one of your friends. People who do these things are sick and will do whatever it takes to continue the abuse. They use scare tactics and shame to keep you quiet. Believe me, I was abused by my Grandfather and it has taken me years to finally deal with it after going through sexual addiction most of my life. I am 54 and did not start to heal until I was 40. I so wish I would have been able to deal with it when I was younger. Then I would have been able to have a somewhat normal life. How old are you? You need to tell someone not in the family. Maybe a school counselor. I would rather see you taken out of the house than to continue being abused.
