Dear [Name],
I am writing to apologize for being deceitful to you. I understand that my actions have caused you pain and confusion, and for that I am truly sorry.
I know that I should have been honest with you from the start, but I was scared of how you would react and the consequences of my actions. I was wrong to think that I could get away with my deceit and I regret not being honest with you.
I understand that my actions have caused you to question my integrity and trustworthiness, and I can only apologize for the pain and confusion I have caused.
I want you to know that I am deeply sorry for my actions and that I am committed to being honest and trustworthy in the future. I understand that I have broken your trust, and I am willing to do whatever it takes to earn it back.
I want to make it clear that I understand the magnitude of my actions and the impact they have had on our relationship. I am committed to being honest and trustworthy in the future and I hope that you can forgive me for my deceitful behavior.
Once again, I am deeply sorry for my actions and I hope that you can find it in your heart to forgive me.
Sincerely,
[Your Name]
