And all of these fears and emotions are completely normal. My sister went to her rape trial when we were both much younger. I'm not trying to scare you but it will be pretty tough. She had to testify against him with him there and because she was too scared, he got out after only two months in prison. Just by testifying, you can put him away for much longer and you won't have to worry about him anymore. You can make sure he never hurts you or anyone else ever again. If you have any specific questions, feel free to ask.
