sticky situation

HELLO IM 20F. I used to make money selling nudes, a while ago i got this dude to help me with it where he does all the talking but i make all the videos and pictures. He talks to the buyers but nobody is getting scammed, everyone recieves their content. Its all me im just not managing it and i get money for it. Long story short i hate him and wanted to cut off all contact and have him delete it everything of me and i dont want him using my identity anymore. I demanded he delete everything and show me proof that he deleted it and all my content that he could have, and he wont. And now he just blocked me. I fully believe he will continue to sell my content and make profit for himself. I need help. I am fully aware of the fact that i should just not have done this ever, i guess people do stupid shit when they need extra money. I just need advice.
