Letter Apologizing For Infidelity

Dear [name],

I know what I have done can't be justified through words. But, I want to tell you that I am sorry for my actions. It was my responsibility to not only be truthful to you but to our relationship as well. However, I have failed at keeping you happy and hurt you beyond repair.

I know things can't be changed, and there is no way to make things right, but genuinely I'm not at peace. The way you came to know the truth must have left you shocked and despiteful.

But I hope you would respond to my calls so that I can tell you on the face how sorry I am.

Sincerely yours,

[name]
