Do you mean telling your families or telling the OP's wife?
For us, my H has told his sister, and I have 2 friends I have confided in. I don't want more people to know. I have enough guilt and shame, I don't want to have it compounded....
and for him, he feels that me cheating makes him less of a man, so he's not really for exposing it all either, except he would love to expose OM, who's getting off "scott free" .... but he hasn't - for me. Irony.
