Sadly yes, these are all potentials.
While we're all dealing with MLC, each person is an individual and their response and handling of it towards the end of their crisis will be as individual as each one of us is.
Just as it is up to each LBS whether the door will even be open to their MLCer.
Tends to depend on the longevity and amount of destruction the MLCer manages to create.
But we hear stories of people getting back together after enormously long periods of time, such as 14 years. Anything is a possibility and depends on the two people involved.
But rest assured, if a MLCer chooses to say with the OW/OM, then that relationship will most likely be one of extreme dysfunction, immaturity and selfishness.
If they don't come out the other side of this thing, then sadly, they will be difficult for us to have back in our lives anyway.
If they do, and we are willing to try to reconcile, then great. But that's no walk in the part according to those that have reconciled either.
We just don't know, which is why all we can do is pick ourselves up, dust ourselves off and live the best lives that we can without them. Whether they can catch up to us, time will tell.
