I have the power to make or break his political career

When I was 15 he was 21. He took advantage of me. Used me for my body over and over again. I ended up leaving school and leaving all my friends because I was so ashamed of what he did to me.
Now I'm 22 and he is 28. I have moved on, I've healed...I'm married with a child.
He has decided he wants to run for political office, and I have the powe to ruin his career. To destroy his life the way he did to me all those years ago. All I have to do is out him as a pedophile and he can kiss his career goodbye before it ever begins.
I never pressed charges against him, and I very well may be out of time to do it now. But he sure as hell would never live down this scandal.
Update:
To be clear I don't know for sure if I want to. I'm deciding. I really don't know of somebody with that kind of character should even be in office.
