I need help

I’m 15 I’ve had 4 relationships each one wasn’t very good. My last one ended June 14 2019 I haven’t dated anyone since then. That boy took my virginity after we broke up we became friends with benefits. We had an on and off friend ship we argued a lot he lied to me a lot and he ignored me almost every time I texted. Anyways today his friend (which is another one of my ex’s) sent me a snap flipping me off and he blocked me I didn’t really care though. Him and my ex were hanging out. I texted my ex I’ll call him d he ignored me I knew he saw that I texted I got mad there’s a lot more to the story but I don’t wanna put you through all of that. I blocked D. After I did I remembered he has some of my nude (Ik I shouldn’t send I made a mistake) I told him to delete them but idk if he did I’m afraid. Sorry if this makes no sense. Am I right for blocking him should I drop him as a friend?
