To forgive someone who hurt you emotionally, try to process your own feelings and identify the emotions driving your pain, such as anger, fear, or sadness. Then try to try to empathize with the other person by considering their perspective. It may help you to let go of resentment and anger. Forgive them in your own mind. You may or may not reveal to them that you forgave them. Finally, set boundaries so that you can protect yourself from further harm and let them know clearly how you want to be treated in the future.
