I am writing to apologize for the emotional harm I have caused you. I understand that my words and actions have had a deep and lasting impact on you, and for that I am truly sorry.
I regret that I was not more mindful of the consequences of my words and actions. I understand now that what I said and did was wrong and that I should have taken more care to consider how it would affect you. I am sorry for not being more aware of the impact my words and actions had on you.
I understand that my words and actions have caused you pain and distress, and I am deeply sorry for that. I want you to know that I never meant to hurt you and that I never intended to cause you emotional harm. I regret that I did not think more carefully about the consequences of my words and actions.
I know that my apology alone cannot undo the emotional harm I have caused you, but I hope that it can be a start. I am committed to taking responsibility for my words and actions, and I am willing to do whatever it takes to make things right.
I hope that you can find it in your heart to forgive me. I understand that this may take time and I am willing to be patient. I am here for you and I am ready to listen whenever you need to talk.
Again, I am deeply sorry for the emotional harm I have caused you.
