Oh boy, where to begin?

So, a couple of years ago, I developed a crush on this girl we'll call J. Now, things were going fine for a while, J liked me back too, so....what happened?

Frankly, I had no idea.

One day, she came to school pissed. I asked here why she was angry. She wouldn't say, but I had a suspicion to why she would say this. see, the day before, we had a political discussion. We all had to give our opinion and respectfully debate with our peers. Now, I'm a hard Republican(trump, border wall, Right views)while she's a hard Democrat( patriarchy, feminist, fat acceptance, left views). This wasn't a problem until the debate, which, despite the main rule about keeping things civil, got a little heated, especially between me and her.

So jump back to the day she came to school pissed. I asked her why. She didn't respond. Now, this kept on for a MONTH. Finally, I grew a pair and decided to joke around with her. One day, when she was particularly angry, I said the following.

"Why are you so mad? Is it your time of the month?"

Let the chaos ensue.

From that day on, she despised the ground I walked on. She would do the following

- try to get me in trouble for any goddamn reason, she even lied about many things. EX: reported me for saying the N word on the day I was sick with the flu.

-succesfully turned all my friends against me for a year, using the excuse that I was "homophobic, racist, sexist etc." Which I am not. Disagreeing with someone over the border wall does not make me racist

- got angry over the tiniest things. 
EX 1:threw a hissy fit because I took "her" seat on the bus(no assigned seats.) I offered to move, but she just gave me the death glare and sat somewhere else.

EX 2: yelled at me because my friend left his banana peel on the table. She told me that he was my responsibility or whatever. I told her to take her complaints with him.

So much shit has happened with her, to the point where other people just don't like hanging out with her anymore. She keeps saying shit like "Oh, finally, the people I actually care about " to her friends. She insults them and disregards them on a day to day basis. Now, with all this happening, I apologized about the "time of the month" comment. three times. She didn't care. She was in it for the drama at this point. She loved drama.

You know how I know?

All of this shit happened 2-3 years ago. All of it. And she keeps bringing it up. She uses it as an excuse! She constantly brings up irrelevant shit and causes controversy just to see a bit of drama! I'm sick and tired of her,but I wonder? AITA? I don't know? Could you guys help me decide?
