AITAH for being friends with my friend's ex?

So my friends, lets call them Ryan and Addie. Ryan and Addie were dating for a few months and a cute couple. We're in high school and they seemed to be sweethearts until Ryan broke up with Addie because he liked someone else. At first i was mad at Ryan and thought he was a jerk until he explained himself a bit more and how he didnt want to hurt Addie, which is why he didnt tell her. I decided i was going to be friends with both since Addie was (at the time) my best friend and Ryan was a decent friend.

Ryan got with the girl he liked who didn't go to our school. She can be called Mia. I'd never met Mia but I talked to her once or twice on the phone when Ryan called her. She seemed to be okay. Meanwhile Addie was becoming a bit of a brat. She was making up rumours about Ryan, twisting some stories and was constantly accusing me of trying to get with him, which i never did and never will do.

Ive started distancing myself from Addie as she's been pretty toxic and is going back to some friends who treated both of us badly. Ryan and I were becoming good friends and he came over one day just to watch a movie. Absolutely nothing happened, we laughed, he chased some of the chickens in my yard and half the time he was texting or talking about Mia.

A few days after that I got added to a gc with Mia, Ryan, and one of Mia's friends, she can be called Isabella. Well Isabella didnt like me and that much was clear immediately. I got accused of trying to get with Ryan and Isabella said some very rude things while Ryan and Mia were silent. In a private chat i told Ryan i couldnt believe what she was saying and made a comment about Isabella, calling her a bitch.

Skip a week or two and after avoiding that group chat (i did try leaving it but kept being added back), and i joined a call for a few seconds because I thought Isabella wasnt on it. She immediately joined and started asking why I was calling her a b-tch and being very snarky. i immediately left the call and was pissed at Ryan thinking he was talking shit about me, instead he explained that he gave Mia his login so she could check he wasnt talking to anyone. And of course she checked our chat first.

I deleted that social app and was just sick of the drama. I thought I was in the clear since it has been a month or two since that has happened.

Yesterday i was on call with Ryan and our friend. Ryan talked about Mia frequently and screenshared as he scrolled through her reposted tiktoks. He then found one Mia had made which was asking what she classified cheating as. And in the cheating section was 'hanging one on one with another girl' 'going to another girls house alone' and i cant remember exactly but i think another was having a girl friend or somethin along those lines? Anyways. We both agreed that it was pretty targeted which frustrated me as neither of us like each other and are strictly friends.

After the call i went to bed and got to sleep, something id been struggling to do all week. When I was asleep I got woken up by ppl spamming my phone and calling me, which already ticked me off. When i finally checked i saw that Ryan had given Mia my number since apparently she wanted to ask me something. I was very annoyed to be woken up by this especially since Mia just said 'I was gonna ask you something but I forgot'.

I told Ryan that I do not appreciate him giving my number out without asking me first and just would like him to let me know next time. I felt my message was polite but immediately I was told 'Okay but f-ing chill cause my relationship is on the line so f-ing pipe down.' I was surprised and increasingly getting more annoyed. I then told Mia than when she remembered she could ask but for right now i am going to try and sleep again. But i noticed one more message from a different number this time. Isabella had sent me a paragraph that was extremely rude and out of line. Here is what she said, i even copied the message from my screenshot: 'Hey girl, I don't know why Ur hanging out and calling some dude who has a gf. Ur being desperate. U got some chick crying BC U wanna be selfish. D Plus the dude is Ur so called bsf ex. Ur weird honestly, who let's there bsf ex over. Anyways, making keep Ur legs shut for a bit and stop trying tO get with other people men. Just make U uglier inside. Probably fix that before the outside'

I was furious, at so many people. At Ryan for giving my number to Mia witbout my permission. At Mia for giving my number to someone else who was a total a-hole to me, especially since I was intending on answering her honestly and putting these stupid rumours to rest.

I immediately blocked both of them but I was still obviously angry. When I sent a screenshot of the message to Ryan he just said 'oh that sounds like Isabella' and when I said it obviously was he just said 'ok?' And hasnt texted me since.

Its the next day and I am still furious. I do not appreciate people talking about me like that or my number being given out to people I dont know. I do not think that because I have a friend who is male, I am a wh8re, which Mia and Isabella seem to be convinced of. Im more bothered by the fact that Ryan doesnt seem to care that much either and seems annoyed at me. I know this is all stupid highschool drama but it still frurates me when people are lying about me.

Am I in the wrong here?
