For those who reunite (21%), the average separation length is 2 years. The 3 year mark is statistically the point of no return, where only outcomes observed were continued separation and divorce.
My opinion about this is that there are very few LBSers who are willing to wait longer than three years.
As well, these stats are not specific to MLC so they might not matter at all anyway.
I worked as a research nurse for several years and frankly was quite amazed at how the "stats" could be fudged to make them sound the way the doctor I worked for wanting them to be (because he wanted grant funding) And this was in a double blind clinical trial where you could measure the outcomes.
There are too many variable to even attempt any kind of empirical research on the number of people who reconcile and we cannot even state for sure that someone is having a MLC. There is no diagnostic test. Most data is anecdotal and all that I have read states that most MLCers will want at some point to return but often the LBSer has moved on.
If you are trying to win a race with MLC, or you have a specific time frame in mind that you are willing to wait for their crisis to end, you will never know unless you wait and see whether they return or not and even then you may not want them.
IANTE stated:
I'm not sure how representative this sample is because people come and go, some with spouses who have returned may not update, and others may create an account then not return to the site
I think it is VERY likely that many people have reconciled and have not returned to the site. Why would people want to remind themselves of this very difficult time of life, rather focus on their reconciled relationship and move on to other things.
