This is probably already fairly resolved, since it seems your mind is partially made up.
But I mean, all of this is going to be completely irrelevant in a few years, a year even, so there's honestly no reason to do anything.
I had one bitch that literally did everything she could to ruin my life, FOR LITERALLY NO REASON. We weren't friends, I have never done anything to her. She fucked my boyfriend, she told everyone in the surrounding three cities that I made a threesome porno and that I was a slut and had HIV/AIDS/every disease ever, she sent me not so anonymous hate on every website imaginable and she even told a guy that I was just friends with that I was telling everyone I had slept with him, multiple times, and I lost several friends/a boyfriend over this. She told my boyfriend I had cheated on him multiple times and told every guy that I was friends with that I was a cheater and fucked peoples' boyfriends. She was a shitty person in general. She lied about being raped to make people feel bad for her, and slept with everyone's boyfriends.
(literally every single thing she said about me was/is untrue btw wowow)
You know what I did to her? Absolutely nothing. Called her a fat piece of shit slut and got on with my life.
She's a fat ugly monkey looking mother fucker and life has already punished her enough; she eventually gave up and realized I didn't give a flying fuck and she was a shittier person than she could ever make me out to be.
