Relationship breakup

Hello sir/madam I want to breakup with my bf but he is not letting me to in a decent way. We've been in relationship in 2016 october for more than a year but my bf was always ghosting. finally in 2018 around March he came back and apologized for everything ... After dragging and being in confusion I broke up with him then. But my biggest mistake that I could ever make was I contacted him again in 2019 September ... After that we've been in relationship till 2021March . In between this time things have been rough and so many incidents happened which made me to doubt him. He usually use to talk to other girls after fight and then tell me all such things by himself to me . I let those things go but nothing got better. He fought with me for more than a month to get physical with him . And yes I was the dumb there that I also got brainwashed by him and I did it too. Not just this he used to fight with me for days asking my inappropriate pics. I am dumb again here that I did that too thinking things will get better. Although I told him but i had to do it because of this continuous nagging. Now in this march he asked for my nudes again and after tormenting me for days he succeeded. But then in start of April 2021 he have told me many incidents of him flirting with ither girls and I am NOT ok with it. Now when I'm telling him to breakup he is not letting me and threatening me in such a way that I'm scared to death that what he will do out of anger. Today i asked him to delete my private pictures but he acted and told me i have never sent them to him and told me that i am lying. After listening to this I'm scared. And now he told me that I have three options : either I compromise and stay in since he do not want to . Or I go in court to breakup and deal with it by law. Or i just breakup and cut off with him and he will consider it "dhokha" I can't continue because I'm so scared of him and now I started hating him the most. I don't want to go in court because none of us parents know about it and I don't want them to know?. And I'm so scared to just breakup with him what if he leak my pictures . He was also asking me for my father's no. But I'm not giving him and now he told me that he will arrange it no matter what. Please help me I'm feeling suffocated and want to get out of this situation.
