When a toxic person can no longer control you, they will try to control how others see you. The misinformation will feel unfair but stay above it, trusting that other people will eventually see the truth just like you did. Meaning. If a toxic person can no longer bully or control you, they will tell lies and gossip about you to others and talk behind your back so that others will see you as a bad person. You might be hurt because of this, but those people they are talking to will later see the truth just like you did.
Toxic people like to bully or control someone, and if they see that the individual can no longer be controlled, they will try to make you look bad in the face of others. This is because they are miserable and can't stay out of people's lives. Toxic people are manipulators; they can do anything to hurt you, even if it's to make others hate you.
You should be happy that you are no longer in their control. Those they are talking bad about you will later realise what a manipulator they are and will see the truth just like you did. No matter how often someone lies, the truth will always come out.
