How do you distinguish between a toxic relationship and a toxic woman?

Ok so this girl I recently broke up with was my first relationship I’m autistic and prior to that had never dated but she on the other hand had she had a relationship with a guy that she would call toxic but she would always go running back to him even after sexual manipulation, name calling all sorts of horrible behaviors. We broke up I never did any of that to her she smacked me in my head, called me stupid motherfucker and bullied me about my autism. She would call our relationship toxic but I’m starting to think it’s really not any given relationship it’s her. She bounces from one relationship to another and in the end turns people against the guy she plays victim
