UPDATE : AITA for publicly humiliating my friend after ruining her relationship?

Its been a couple days since the 'incident'
But wanted to let you guys know whats been happening.

After I posted the story with all of Tim’s messages, my phone blew up. Like, I’ve never had so many notifications in my life. Most of our mutual friends were messaging me in shock. A few apologized for believing Sasha and said they had no idea Tim was like this. A couple of people even told me they’d noticed Tim being weird or flirty with other girls before, but they didn’t want to get on Sasha's bad side by saying anything. So apparently, this guy has a history.

Also on top of that, I always knew Sasha had a bit of a temper and sometimes overreacts. I never thought it'd be a big deal though or was a red flag.

Anyways–The weirdest part is that Sasha still tried to defend him. She texted me this long, angry message saying I’d “violated her trust” by telling everyone their private drama and that Tim was “joking” in his messages to me. She even fully said, “You should’ve come to me instead of trying to humiliate me.”
Which like… I DID go to her?

I told her flat out that I didn’t post the story to humiliate anyone—I posted it because she and Tim were spreading lies about me. AND there’s literally NO WAY to “misunderstand” a text like “I need you so bad.”

Apparently, a few of Sasha’s other friends got involved and confronted Tim directly. One of them added me to a group chat and said, “You’re not the first girl he’s done this to.” Turns out, Tim has a pattern of sending these kinds of messages to other girls while dating someone. He’s even tried to slide into the DMs of one of Sasha’s old friends. When Sasha found out about that incident a while back, Tim convinced her it was a “misunderstanding,” just like he’s doing now.

Also found out that Tim didn't miss the cut off, so even though we are of age he is still like supposed to be in college..

I feel bad for Sasha because it’s clear Tim has manipulated her, but I’m done trying to help someone who refuses to see the truth. She’s still with him, by the way.

Sasha's blocked me on everything, and in return i blocked Tim on everything
Thanks for listening guys.
