Please don't take offense but I found that line of reasoning offensive; short sighted and presumtuous.
I still believe that R's are what you can make of them. And your ability to make something of any R (i.e KEEP the excitement) depends solely on YOUR ability to know what excites YOU and THEM and work on that.
To take the defeatest; helpless; and almost victimish stance that "R's run their course and that's that" is giving up before you played the game.
Why get into the R in the first place? For the thrill of the start and the pain of the end? not for me, thanks.
And that the other person left the last relationship to be with us doesn't prove this position. All it says is that we know that they (like our leaving our last R's)either discovered: -there was a true incompatibility -WE failed to create and maintain boundaries to get what WE needed from the R -THEY failed to do the above as well OR couldn't accept the others' boundaries -We and/or THEY had inner issues that developed into an insurmountable R obstacle. -Any combination of the above.
"The fog" which is spoken of is the failure to recognize/acknowledge any of the above and/or be under the influence of the "Love Drug (PEA)" which prevents ANY analysis of the above. I would also consider that the attitude of "R's run theit course and that's that" IS a attributeable and a symptom of the same "fog"
2x4? 4x4? Yes.
My opinion. I have a similar opinion about the "term" MLC.
