AITAH I am male (18M) and this girl (18F) has a crush on me and it's really stressing me out.

A mutual friend of mine introduced the girl from me, a girl from another class. At first she was really really nice and she was friendly towards me then soon we started talking. I didn't see her as anything special and genuinely just wanted to be a friend to her because she was really cool. One day she walked up to me during a sports festival and told me I was cool with a blush on her face, from then on I knew something was wrong.

She started talking to me very often and kept texting me and buying my friends free stuff in front of me and buying me even more stuff. Recently the moment she found out I was looking for this new spiderman figure for my spiderman collection she immediately bought it for me and I felt pretty good about it. Though I still wanted to stay as just friends and at one point I was just casually going through a day of school when suddenly a friend of mine confronted me and I didn't know why until she started talking to me. It turns out that the girl told my friend that I dismissed her over something she discussed about her past. I did not know when I dismissed anything because I was genuinely in the dark about the situation because I was never told anything about her past. I felt really down in the dumps afterwards and I didn't know if I did anything wrong but then two of my friends gave me the benefit of my doubt and looked through the messages after I texted them for advice, they told me that I did nothing wrong because I was simply scolded with no prior context, but either way I simply apologized and went on the next day.

The next day in the middle of classes I was just sitting in class then suddenly she starts ranting to me about her grades then since I was focused on my class I responded with an sticker and she crashed out and ranted to her friends telling them that I laughed at her ranting even though the emote I sent was not even remotely close to ranting it was just the chill emoji! Her friends confronted me and after that my mood soured which leads to now. I'm so pissed off that I'm ghosting her and wondering what I should do with the situation now.
