PLEASE HELP !!!!

Hi. My name is Sami and I'm in high school. I know this is app is suppose to be a period tracker lol but a friend suggested I get on this and tell my story. So I had this boyfriend and I loved him. A lot. And he was basically my entire world. He was controlling and overly jealous and it was terrible. I was head over heels for him so I didn't mind at the time. I'll spare you the gruesome details but one day, he "sexually abused" me as my friend calls it. And I still didn't break up with him until I heard that he wanted to break up with me a week or two later and that he's been over me for a while. So I dumped him. And it's been a month. I started actually get over it all and then he started spreading that I cheated on him and all my friends stopped talking to me and it was terrible. I need revenge. I need a plan to take him down so I came to you guys for help. Any ideas?
