I agree w/ Solara about the potential dangers of a confrontation. I've never been really ready for a confrontation. Besides he lives about 1000 miles away.
So…roughly 15 years ago I stumbled upon a factoid about how my state of former residence allows anonymous reports about sexual abuse, even years after it happened (and by that time it had been over 30 years). So I wrote a letter to the captain of the state police that managed these complaints.
This guy was great. It turned out that his office was located in the same town where my abuser lived at the time. The captain called me on the phone, told me they "ran" the guy through the database. Nothing turned up which of course only means that he's never been convicted or arrested. But then the captain took the extra step of "asking the locals" (meaning local, not state police). Nothing turned up there either. I felt like I had done just about all I could at the time.
Some years later, I found my abuser's address and wrote him an anonymous letter. I wanted to know I was still alive, that I hadn't killed myself, and that I remembered what he did, and that I reported him to the state police. I also told him that I had the addresses of his siblings, friends, and daughter, all of which is the truth. I said that I might, at any time, write his siblings or his neighbors and tell them just who he is. I told him that I wanted him to be looking over his shoulder for the rest of his life.
I can't recommend doing what I did, because there is risk involved, lots of it. I made sure that there was nothing in my letter that would reveal who I was, then mailed it from another city from where I actually live. Still, there is a possibility he could figure it out. And I'm OK with that; as far as I'm concerned, he can bring it on. But, in your case, you have to prioritize your own safety.
