She squirmed and b*tched and moaned and screamed bloody murder at first, that I refused to sit down and talk to her. Eventually, over the course of a few weeks, as she saw that I was NOT going to be either bullied nor sweet-talked (and she tried both approaches) into sitting down and having an R talk with her, she eventually stopped trying.
I confronted my wife within 24 hours of having proof she was having an affair.
I exposed her affair within 24 hours to our adult daughters, and within two weeks to her family and her employer.
I re-confronted her on Day 60, and laid out a "No More Deceit" boundary, telling her "either you tell our daughters and your parents the truth about your relationship with (OM), or I will." I had evidence, and I told her she had five minutes to decide. Within two hours, she had told all four of them the truth -- that she wasn't "just friends" with OM, and that Puppy hadn't been lying when I told them she was having an affair.
About a week later (around Day 70), I filed for divorce, after my wife stubbornly refused to end her affair.
On Day 90, she ended her affair, and asked "what will it take?" to reconcile. I laid out my short-list of non-negotiable boundaries, and we reconciled.
There were several fits-and-starts after that, with the divorce initially being put on two 3-month "stays" before finally being withdrawn. We also separated for a couple of weeks about a year ago, and agreed to date other people, but that was short-lived, and after one "date" (drinks with a former co-worker) I agreed to move back in with her to work on our marriage. We did some MCing, still struggle with the SSM thing, but have remained great friends and partners ever since, and celebrated both our 25th wedding anniversary and the birth of our first granddaughter this Spring.
Interestingly, when my wife tearfully asked for reconciliation (and thereafter), she told me that although she HATED me at the time, and was LIVID with me for exposing her affair, she understood why I did it, RESPECTED me for it, and THANKED ME for fighting for our marriage!
