Confrontation can be so tricky. Ask yourself if you are strong enough to handle standing infront of the person you hate the most? If you are, then yes, confront him. It's actually a good thing that your mom knows because it might be easier if she is with you. I would not do it alone. let your mom do what she wants do, if you don't want to be involved, tell her that. There should be no pressure on you to confront this person, if you feel you are better of never doing it, do not feel ashamed or weak, it's your decision completely. A lot of people never confront there abusers and there is nothing wrong with that. They have suffered enough already, it's not their fault and they don't have to attone for anything. Just lookout for yourself, do what you want to and feel comfortable with. I wish you all the best.
