Why would your wife fall under that category? Are you about to move on? Do you think she will not come out of crisis? Yes, LBS tend to grow and a point comes when the LBS and the MLCer are not compatible anymore. Of course that, like with everything, there are exceptions. And, yet, we are told that MLC is a growing process and the MLCer will be a more mature, better person when the crisis is over. In a way, yes, but in my view they still have not grow as much as the LBS.
All MLCers I have come across, in the board stories and real life, were not able to call off the affair. One of the characteristics of MLC affair is that it does not end by the reasons normal affairs ends (spouse finds out, children are taken in consideration, the cheater realises the mistake). Since both you and your OW called it out it is a different affair from the ones our MLCer have.
The difference between MLC and midlife transition is important. The first is a years long situation with gigantic consequences and damages, the second can include an affair but is a mild thing. Most sites and blogs label midlife transition MLC and say it last about 6 months to a year and that the affair will soon end. That is not the case with MLC. I understand the affair can be like a drug but I find it very hard to believe that those that spend several years living with OW/OM do not see what they are doing and that they fail to see what OW/OM is. And once one is living daily life no more fantasy, so, a MLC affair really is a odd thing.
From what we read here on the board and from real life MLCers I know children do not factor in the decision of leaving/staying. Children may cross their mind but they do not stop a MCLer from leaving, from carry on the affair or from live with OW/OM.
MLCers leave in a world of emotions, but, again, it is a little hard to believe said emotions can run someone’s life for 5,6,7,8 or more years.
