What To Do In This Situation

location: New York

Hello

A couple years ago, I met this man who was an adult and I was (and still am) a minor. We dated for a while and He made me feel really loved and everything. He’d often ask me to send him nudes which i stupidly did and he saved them. He was quite manipulative and would always say like “you don’t want to please me” or “ you don’t love me anymore so you aren’t sending any.” He’d also threaten our relationship often which destroyed me mentally and made me do things he wanted me to do. He insulted me often which made me quite dependent on him. We broke up a few months after because it just didn’t work out because I felt he was only with me for them and in general we weren’t very compatible. I asked him to delete the nudes which he assured me he had but after a few months, he came back in my life just to threaten to leak everything to all my friends if I didn’t send him more. He ended up sending them to a few that I knew personally who assured me they didn’t look and for me to report it instantly but I’ve always been way to scared to get involved in legal things as my parents don’t even know about this. I know I’m stupid for sending them in the first place. I know the consequences as we’re always told not to do things like that and yet I still did. He still holds them to this day despite reassuring he deleted them. I was really young and it’s been a while since then. I’ve matured way more than how I used to be and I feel like I understand more now and it really makes me uncomfortable to know M still has it. What do I do in this situation?
