Long read warning. It's been nearly a year since this woman is bothering me. I would give you the entire story. We met at college. She liked dragon Ball which I did too so we became friends over that. She was very fun to talk to initially and would always initiate conversation. She was cute but was too thin for me ( I spanked her and felt bones) so I just kept cool. So once she asked me out to go drinking. For which she paid and we had a great time. We kept hanging out eventually she said she didn't want to talk to me anymore. I asked what's wrong? She said that I should figure it out. I said okay. She got pissed off and said it's because I care about the gym too much and she was giving me a chance with her despite I have no money. I called her malnourished and ended it. But felt bad as I body shamed her and she was bullied for it. I apologized to her after which she hugged me but the next moment she went bat shit crazy and told me to stop following her. I was like wtf

She sent my friend 6 essays about me. Despite claiming to hate me she sits exactly behind me during class and keeps staring at me if I sit elsewhere. She wastes no opportunity trying to touch lol. Like she would bump me even though there's clearly enough space. I had repeatedly asked her to make peace but she doesn't listen. I feel like punching her somedays. What should I do guys?
