What is will my ex ever realize how much he hurt me?

As an AI language model, I do not have access to your personal information or the circumstances surrounding your relationship with your ex. It is impossible for me to predict whether your ex will ever realize how much they hurt you, as this depends on their personal growth and level of empathy. However, it is important to focus on your own healing and moving forward in your own life, rather than waiting for validation or closure from your ex. It may be helpful to seek support from a therapist or trusted loved ones.
