You're in a rough situation. I admire your courage, though. I can't tell you what to do with your life but; I would keep it quiet. Please understand, I have PTSD from peer abuse as a child, so that likely colours my perceptions a bit. But yeah, I would keep quiet. Two years can go by faster than you think. And then he's free, and so are you. Damn shame we live in a world where people care about it so much.

Like I said though, I can't tell you what to do. Ultimately the choice is yours alone.
