The six month thing is for the average affair, averages are not the norm, they are a mathematical representation of what could be normal.
The norm is that affair duration varies dramatically. The variables are the intensity of the affair, the length of the marriage, the problems in the marriage, the amount of chliden you have together, how well the WWS bonded with them, etc.
The idea that you can box all affairs into a six month block isn't realistic.
Many probably don't last long. I think the six month thing is more about the survival rate rather than the precise time it ends.
My wife has been having an affair for almost two years, and others on forums I have been on for having an affair for six or even seven years. It happens.
The thing to focus on is your divorce busting strategy. THAT is the variable you have control over. And I would argue its a powerful one at your disposal.
People who db well can fight the affair and keep it from growing or they can NOT db well and the affair will thrive. How the spouse handles the affair has a large impact on the affair's survival.
Rather than waiting for the six month block, ask yourself what else you might be able to do that might help influence a reconcilliation for you and your spouse, which will end the affair eventually. The dbing is to promote reconcilliation...reconciliation ends affairs.
That being said, there are tactics and things that can be done to attack the affair outright, Michele Davis doesn't touch on those much, and I would be cautious about using them. THOSE can backfire.
Never mind the six month time frame, its a ballpark estimate at best and is NOT lilkey to match your situation. Only one or two relationships meet the average, the rest fall above or below the line...the likely hood of you being ON the line is slim as the line itself.
DB your heart out, its your gift to yourself, a better and happier life. If your spouse decides to join you, its a beautiful thing, and oftentimes they do.
One of the best resources for Infidelity is "Not Just Friends" by Shirley Paige. She studied infidelity for twenty years. And the questionairres Paige used were done anonymously and handed out at the airport, to get the largest demographic sample.
Most don't fill out the questionairre, but many do...read NJF and she discusses her findings in detail.
