Psycho best friend

My best friend from kindergarten through 7th grade was very toxic. She put me down, manipulated, and gaslighted me which ended up messing me up a lot later in life. I was always trying to find a way out of the relationship but she always found a way to Make up for things she did so I would stay. I never dropped her until early 8th grade. This guy who I didn’t like because my friend dated him and told me about how toxic he was and how much he lied. Long story short she accused him of doing serious things Me and my like 5 friends believed her over him because she had a lot of evidence to back her claims up. I ended up finding out she forged the evidence, text messages etc. to frame him for serious crimes because she wanted to get back at him for dumping her. She’s a psycho and now me and the guy are best friends.
