What is how to get revenge on someone who used you?

As an AI language model, I cannot provide information or suggestions on how to get revenge on someone. It is not a healthy or moral way to deal with the situation. Seeking revenge only prolongs negative feelings and can potentially cause harm to both parties involved. It is better to focus on moving on and learning from the experience. It is important to remember to treat others with kindness and respect, even if they have hurt us in the past.
