Are you serious? This thread is MLC.
When you meet somebody in MLC who truly is in MLC, then let me know. I think you are missing it. I was clueless about MLC.
When somebody is in MLC, the LBS truly has some work to do to get a handle on it, but a few clues might be:

Throwing out Morals, Values, etc.
Behavior that is way out of norm for the spouse.
People at work see it.
IC can see it.
MLC's family can see it.
LBS's family can see it.
Kids can see it.
They don't have a clue what it is, I don't blame them. How could they? The IC knows what it is though. This is very real.

All of these people that know the MLC'r, are not lying. They are not hallucinating. It doesn't happen to everyone in the same manner as the people posting here though. Most people get through midlife without the crisis. If I had one I did not get the memo.

I am not trying to get on your case. Maybe not everyone that is on the MLC threads have an MLC person on their hands. I am willing to bet most are. I just get the feeling that you don't want to acknowledge the fact that this exists. What is your motivation to post in this manner? Are you angry at someone?
When people are angry they typically don't want to offer help?
Maybe its just me and I am not getting the point.

I know this is MR's thread and I don't want to hijack it so I will stop here.
