I recently ended a year and a half long relationship with an abusive boyfriend. He was both emotional and sexually abusive. We never actually had sex, but we were sexual with each other, touching each other and (twice) oral sex. He would never take no for an answer and in my memory there has been only twice where he said to tell him if I was uncomfortable with something. Even then he didn't ask for consent. He would make me feel like I owed him sexual favors by being extra nice to me and stuff like that. A lot of times he would just do what he wanted without asking, and wouldn't listen to me when I told him no. He often moved my hand to touch him where he wanted, and attempted to push my head down to perform oral sex. When I resisted, he only pushed harder. There was even one time where we were somehow on the topic of sex, and I asked what he would do if I started crying and not wanting it, and he said something along the lines of "then I'll cover your mouth and ignore you until I'm done." I still don't know if he was joking. He would tell me what to wear and what to put on my burgers. He would make me pay him back for dates. He took me to Walmart to buy a new swimsuit because "I don't want you wearing all black." He would get overly jealous of my friends until I stopped talking to them altogether. 
Thinking back on all of these things has made me spiral into a depressive episode, and school starts on Thursday. He is a legal adult in my state and all of this took place before I turned 16. What should I do about all this?
