"Globule, does she know the details to the point of the OW being the one to end it? If not, I would play that down." Yes, she knows it. I pretty much confessed to all the important details, just leaving out some specifics on the advice of the C who said that the W didn't need concrete images in her head the rest of her life. Was that bad advice?
You have to remember that OW really didn't break it off either. Her husband found out and forced her. My W does not know that detail. I didn't want her to worry about what OW's husband might do. That is another reason for keeping tabs through the mutual friend. I might get some advance warning if he decides to go ballistic. I'm guessing that if he hasn't after a month, he probably won't.
I tried to make up for not being the one to break it off by confessing. I could have probably never said anything to the W and she would only have had suspicions that might have died off after awhile. Who knows? Of course I am not making myself out to be a saint by confessing. It was partially out of a sense of guilt, and partially out of a deep depression.
