I need advice because idk what to do

Also I know this is off topic but I just kinda wanted to get it off my chest it’s nothing bad but it’s just in my head rn and maybe if I wrote it would make me feel better but idk but this happened last year but it still wasn’t the best. So last year I was in 8th grade and this kid I was friends with before but we weren’t the closest and honestly he was really perverted and tried to get with every girl in my grade well one day he went up to me as asked for my number and ofc I said yes because I thought he just wanted to be friends but like every time we would talk he would be flirty and send hearts and I just did cause I thought it didn’t mean anything. Well one night he said I have feelings for you and I friend zoned him a couple of times but he was still persistent and one day around Christmas he wanted to date and I was tired of him asking me so I basically caved in and we dated for 4 weeks and if I’m being honest it was the worst fucking 4 weeks of my life and sorry for the profanity but I’m just being honest and he kept saying I love you and he was telling everyone we were dating and he would literally find where my classes were and meet me there and if I didn’t come he would have a fit and one day he kissed me on the cheek which sounds not bad but I ended up crying because I was so un comfortable and I was honestly kinda depressed nobody really knows what happened except for this one girl the same thing happened to her and one day in class she had a panic attack and she was talking to a friend when he came up to her and was like I’m so sorry about what happened etc and later texted her and she thought that he was trying to date her again and he said no I have a girlfriend and she was like who and he said me and showed our messages and then she later texted me and was helping me etc and when they dated he would make her give him a blow job and he also wanted to kiss her she didn’t want to do that but still did and I think he was getting to the point of wanting to do stuff with me but luckily I broke it off before any of that happened but she went through the same stuff so she was helping me before it got worse and I also wasn’t eating when this whole thing happened cause I was so stressed and like an emotional wreck but one day I was ready to end it and in gym class he would hold my hand and I wasn’t comfortable with it but still did and every time we would play a game I would try and do something different to run away from him but he still would follow me and one day this girl was like are you guys dating and he said no I’m her dog and he would always try to hangout with me but I’m not allowed to date and plus I would make up excuses to why I couldn’t etc but it was just horrible and I tried getting into a relationship this year with a guy I actually liked and I realize now I’m just not ready for a relationship cause it causes too much stress and idk if it’s because of what happened last year or what. So that’s why the single life is better for me. And also when he went to France on a school trip he would put his hand on one of my friends leg and she told him to stop and he still kept doing it. Also when I was “dating” him I would always get in so much trouble cause I stayed up late texting him when I wasn’t supposed to and then his “sister” found out we broke up and she was like why did you break up with him and saying how I broke his heart and that kinda stuff but I didn’t give her the full explanation I just said I wasn’t ready for a relationship and then she was like well you shouldn’t have gotten into it but it caused a lot of damage for me a little bit like it honestly made me depressed and i always cried myself to sleep but after the break up I avoided him at all cost cause I felt disgusted by him and one day he saw me and was like hey I haven’t seen you in a while and he put out his fist gave him a fist up and just left. And afterwards I deleted his number and have never talked to him again and don’t want to. That’s why I’m glad I don’t go to the same high school as him. Also this happened again with a different guy around December except we only texted and at school I didn’t look at him or text cause I just wasn’t ready and later on I decided to block him so that this thing doesn’t happen again. But honestly after that happened I try not to count it as a actual relationship cause it was a really shitty one and almost toxic or like one sided ig.
