AITA for being fake and trying to cut off my ex best friend?

For context, I want to state that I do not think I am the asshole. But I am posting about it to get other’s opinion and to see if I’m possibly also just overreacting.

I (21f) had be friends with Rylie (20f) for about a year. And throughout our friendship I had noticed she would constantly lie to me. They weren’t huge lies but they were still small ones, and enough of them to compile together and frustrate me. I usually let them all go but after a while once it started to become a lot or maybe a bit bigger like lying about things that were said or where she was or went I would call her out on because I was getting tired of it. When I would do so she continued to lie about it more and how I was wrong even when I had the evidence. At that point I had already stopped talking to her and ghosted her for a little bit since I didn’t want to deal with her bs any longer. We had finally hung out again after about a month and I spoke to her about her actions which she apologized for and admitted to lying about, so everything was fine after that right? NOPE! She still continued to do the same thing and act like I had no clue, but that’s not even the biggest issue. Come to pretty damn recently around October/November to January into Feb./March she did worse things. First off she originally had taken a $80 hoodie from my house and took it home with her, her sister ended up taking it to college with her and at that point I had already been asking for it back for about a month. Come to find out the hoodie was given away and sold without my knowledge. And it wasn’t like her or her family didn’t know it was mine, I was pestering them all about it because I wanted back but they all lied to my face about knowing where it was and that id get it back. Her mom paid me back for it but that still doesn’t make it okay in my book. Secondly for my 21sr birthday she completely ditched me. I had noticed her texting her bf on her phone telling him to tell her when he wants to leave so she can make up an excuse for why she left, so I obviously called her out on it telling her how fucked up that is and wrong. She was of course in denial and promised me she wouldn’t leave…she still left after crying silently on my couch because she really didn’t want to be there. I ended up going to the bathroom and when I came back out she was gone. And lastly even after all of that I continued to try and be friends but while she was spending the night at my house she locked me out of a room in my house and talked shit about me to someone she was on the phone with and telling them I was the reason for all of her issues and actions she had been making. That was honestly my final straw and since then I ignore all of her texts and calls and don’t ever speak to her. She recently texted me asking if she did something wrong and I told her I didn’t want to be friends but she continued to say she’s changed and she’ll prove it to me…but like I just said I didn’t want to be friends nor hang out with her so I don’t understand why she’s not understanding my clear feelings.
