Toxic friend ??

So when I was in high school I had an extremely toxic friend who whenever I cancel or show up late or anything like that she would freak out and be controlling make me feel horrible and one time when I went to college she visited for a weekend and she literally made my life miserable even my roommates say so. We all went out for a night but she wanted to go back to my place because she didn’t wanna be out, and when I told her to wait a couple minutes for us To subway home, she threatened to have sex with somebody in my room and have a bunch people over to my house anyway she end up going back to our hometown which is an hour away from my school. Since that day I haven’t spoke to her, even though we were best friends for years it was the final straw. That was October of last year and even though that was extremely toxic I feel like we’ve had our time away from each other and I want to reach out to her again I just feel like for by not speaking to each other for a while we’ve grown but she hasn’t made any effort to reach out however tonight I did. Any advice?
