Confronting the guy who knew better

I made a post a while ago about a guy asking me for nudes while I was under age who used to be in a semi popular band. I have his Facebook page pulled up, and each time I go to start a message confronting him, my chest gets tight and I get so damn nervous. I have no proof anymore due to not having the phone that had the messages. I checked my old Facebook and the messages on there are gone(assuming deleted by the guy I was dating back then who hated me talking to this one) so I'm scared that if I do confront him, he'll shame me or act like he doesn't know. Or maybe he'll plaster my picture all over calling me a liar. I'm terrified. I have no courage to do it now..
