I have to make a tough confession...
I'm really keen to know why. What do you confess?
I'd like to say that I had a thing for someone's wife.
You should make the difficult decision to tell them your confession. Holding it in will just end badly.
Nah, it's too late already. I sent her a letter so she is going to find out.
Well it sounds like you made that choice so now you should just be ready for the fallout once it is known.
