So...me and my bestfriend, we were hanging out with our group and decided to do some trends, she took my phone to log into her official Instagram account so she can text her friend, she had removed her account from my phone after. Next day, I found out that she had stolen my ID password, logged into my account, and read all the chats of my friends, including her ex-best friend, who is also my best friend. When i confronted her she kept lying until i sent her the proof of her mobile device logged in my account and guess what she confessed and That’s not all..I still have no idea how her second account was logged into my phone. She blamed me, saying that I had done the same thing, and that we both had logged into each other’s accounts, claiming it wasn’t that serious. I immediately ended my 8+ year friendship with her. Later, when everyone was blaming her, she started playing the victim, going to my other friends and telling them what happened and putting the blame on me trying to twist the truth making herself the victim. The same night when i found out about that she had logged into my account I had confronted her, she posted a story on her Instagram story saying that "we both had done the same thing i know my way was wrong but atleast the truth is here" one of my friend took a ss and sent to me, i never replied to her story or try to explain things, because my friends trusted me that i would never do such thing ever. Even my classmates were in disbelief.

Please tell me, did I do the right thing? I feel like maybe I overreacted and shouldn’t have cut her off immediately, but at the same time, I also feel like what I did was right.
