y'all I rlly need advice/srs

I know this is rlly long but I don't know a lot of people I could talk to about this so pls read through the whole thing and give me some advice if u can I know it's long sorry. 

so back in freshman year (grade 9) of highschool there was this rlly outspoken kid let's call him Jordan. Jordan was always talking a lot and blurting out in class and nobody in the class liked him okay. One day we all got assigned a project and nobody wanted to be his partner so he came to me and he asked me to be his partner. I didn't have any friends in that class and I needed a partner anyway so it's not like I had any reason to say no even though he made me a bit uncomfy. It went pretty okay I asserted myself because he kind of started slacking off but we got on track and it was good. after we finished the project tho we kept talking and I considered him one of my friends. But one day he said something kind of iffy about how he liked family guy, he said "it's kind of racist but I like it so who cares" and I called him out on it because I'm mixed and it was kind of out of pocket of him and he said "oh, okay never mind then." then he proceeded to talk about how not racist he was and how he would always call out his grandparents for saying the n word and mocking asian people and I was like... uhm... Okay? Thank u for ur service?? He would always sit really close to me which wasn't really his fault because the chairs in the class were just like that but he would always lean really close to me an try to look at my phone and I was too scared to call him out on it but I shrugged it off. next day he started talking to me about his life and how he had a girlfriend but it turned out she was just using him and was cheating on him with another guy. She only dated him to please her parents. He proceeded to ask me if I had a boyfriend and I reluctantly said no, I didn't wanna give him the wrong idea because I don't even swing that way but I wasn't sure how he would've responded so I just said no and moved on. Jordan and this other kid idec i'm gonna use his real name because he's such a piece of shit human being and I don't like to talk shit but f-ck u cody. Jordan and Cody would always get into it in class and one day Jordan was just showing me some family guy clips and at this point I was just rlly uncomfortable with Jordan because of what he had said so I was kind of being distant. They started fighting and Cody literally asked Jordan "how many times were you fucking dropped" and that holy shit pissed me tf off. Jordan I'm like 99% sure is autistic he never said anything but I personally know other autistic people and they'd spoken to me about their habits and tendencies and for Cody to say that because I'm pretty sure he knew too was so shitty. Everyone in that class rlly treated him like shit and he deserved basic human decency thats why I rlly wanted to be friends even though we didn't have anything in common and I was rlly excited about it actually it was about time I meet new people. But I just rlly didn't feel safe around him. The next day rlly put me in an awful position though. he came to me the next morning, and showed me a text he had sent me on his phone (i had blocked him because I didn't rlly want to talk to him) and it was just a short paragraph about how he had feelings for me and wanted me to be his girlfriend. I told him sorry, I'm gay and he handled it well. He said it was fine and that "this always happens, every girl is either cheating, dating someone, or gay" and that day during class I just told him outright I was uncomfortable and I needed space. He said okay and left me alone for a few days, in the meantime I had reached out to the teacher and told them to move him if he ever got near me. I also had my friend help me tell him that I didn't wanna talk to him anymore because he made me uncomfortable. But he kept trying to talk to me. I snapped at him and told him myself "you make me uncomfortable" and we haven't spoken since. I've felt like such an asshole for so long? keep in mind I'm transmasc and I use he/they pronouns but I have to present feminine because of my parents and there's a lot of assholes at school so he was under the impression I was a whole she/her. I also don't think he would have respected me if I told him that either. It's one thing to be tolerant of gay people but it's another thing to be accepting of non-cis people... I'm not 100% sure why he made me uncomfortable? Maybe it was because of what he said and always addressed me as she/her. But everytime I would see him I would literally just start having an anxiety attack... Am I an asshole? This was a while ago but I still think about it sometimes and wonder if it was justified. If I'm an ass please just tell me because irdk
