I had a very similar experience to your's mark. I waited 30 years to think about exposing the abuser who was very much like yours. I asked myself what I wanted out the exposure besides stopping him and it allowed me to get some very good therapy for the second time to explore the issue. I think most of us want to get control back. I have a very high profile position and going after my abuser would have ended up on natonal tv. I was willing to do it but knew it would cause alot of pain for many people who love me. and winning after 35 years with no witnesses would have been tough. it would be awful to have let this other guy off again!! anyways, I didn't do it but would never advise someone else on this . you need to figure this out yourself. good luck.
