Whilst I agree with this somewhat, it has to be said if your spouse is truly MLC and I am doubtful that all who are labelled MLC are,it is truer to say the man we knew,we knew better than anyone else.
People change-we all do it's inevitable our attitudes change as we go through life. I think for most of us our core values remain the same though.
Many undergoing a MLC do not emerge the same people they were before. Yes we can wait the 2,4,6,8years whatever the current time guide is and still not see the spouse we married.
If we have not made the changes we needed to make to ourselves, to become better people to be responsible for our own happiness whilst waiting/standing nothing will have changed and our marriage even if restored will still have the same problems that made the spouse leave in the first place.
As LBS's there is a tendency to see the marriage with rose col. specs and view the OP as the devil incarnate. That may or maynot be true,we still need to do the work.
Just maybe people who advise us to move on see characteristics in our spouses we never saw (but were there all along) because of those rose col specs.
Imp's post still has the most excellent advice.
