Story (I need advice too)

okay so basically, I had this guy bsf at the start of this year, and we were really close but compared to my friends and him he didn’t have a grungy style bc he was a « popular » guy. So no one rlly liked him bc of that. Then he started telling us that he was gay, and we all supported him bc half of us aren’t even straight 😭, so then like a few months later I get a gf and tell him, he sounded jealous and a few days later he tells us that he got a boyfriend named Eric we were happy for him ig up until he tells my gf that Eric raped him and he told her not to tell us but she told us ofc, so we talked to him abt it and he said « no it’s not raping bc I liked it, plus he’s very hyper sexual » broski, what?💀. So we explained to him that he should break up w Eric so the guy is like « no I love him » and all that so we left him alone, and then Eric breaks up w him, and atp we’ve seen and heard Eric and knew that  he was a real person. That’s nice ig. Then on a random Sunday, me and this the guy bsf (let’s call him yellow cuz no one likes yellow) are on a field trip at school and he’s acting « high » and cringe, he started to put his head on my lap, which was normal, and asking for hits out of my vape a lot which was annoying, also he pretended to lick a pu€€y by forming one w his fingers and he was turned on? (Littarly ew) so I ignored it although I was really pissed off abt I all rhay for some reason but ignored it, then the next day he tells us he can’t be friends cuz he had come out to his parents as gay and then got caught watching gay p0rn but that wasn’t true at all (he did get caught and he did come out) he stopped being friends w us for his brothers reputation. Like, child, what? 😭😭🙏🏼. So my friend group (we were 4 including yellow) and I didn’t care, but then yellow comes up to me at school around 5pm just to tell me that he leaked my friend and I’s secrets, (only our sexuality technically cuz again, none of us r straight). And we’re open abt it so we didn’t care, but then he makes rumors rhay are bad. Like for example he said that I had a dildo in my room. IM 13 BRO FYM I GOT A DILDO IN MY ROOM. So we exposed him, bc apparently he got raped by Eric? And his brother? He liked a guy in 11th grade? And he’s a pervert. And when we exposed him he started chasing us so we ran separate ways and he chased me and took my hair and tried to strangle me so I kicked him in the balls and slapped him across the face, he started crying out of anger and calling me a whore. (At least I get bitches tho, I mean, I get more girls then him as a girl, he had to FAKE getting raped) anywho, so we got suspended, a few weeks later he tries to talk to me, apologizing for everything, saying that he’s sorry, and was just mad and has bad anger issues (cap), so I forgave him but little did I know he was trying to get more dirt on me, but he didn’t get shit bc I broke up w my gf bc of what happened. And he had nothing against me atp, but out of nowhere he started becoming popular he hung out w the guys who used to make fun of him bc there was this rumor that he and I f-ed in the bathroom thay went around the whole skl. So he started making more and more rumors. So I just exposed his messages to a group of popular girls, told all of his crushes the inappropriate things he said abt them, and showed a few guys the messages too. He doesn’t know it yet tho. And then he has the audacity to talk maddd sjit abt my parents when he beat me up for telling ppl smt that HE told ME? he’s fucking crazy. Anyway. What should I do abt all that? He bullies me w his friends and makes more rumor but adding my parents in it.
