I wish I could have had the opportunity you're being presented with, to be honest. I'm not saying go do it, because that's your choice, but if you feel that you can, I think you should try.
I reported the person who had raped me many times over the years (my father) as a young adult, 4 years after the last rape. There was no evidence to hold against him by then, so it never went to court. Would it have been difficult to see him again, particularly in that context? Yes, it would have. No one is going to deny that. -but it also would have been empowering, to be the one who's testimony against him sealed his fate. It would have also brought me peace of mind, because I know I wasn't his only victim, and if he could be stopped and locked away, I might be saving others.
