I just want to add one thing with is keeping with the spirit of this post, but it is slightly tangential. It is probably one of the best pieces of insight that I got here and every LBS should know this. The credit for this goes to AnotherStander who laid it out in plain terms when I was in the throes of my confusion. His insight really opened my eyes and I am putting it here in my words (I will try and go back later and find what AS exactly said)
Quick caveat: I know some people on the board don't like using the word 'fog' as it stands. They think it's too reductive and maybe negative to portray the WAS in that light. I am using the term 'fog' here to describe the mindset and attitude rather than saying that it is negative or not. For me it represents confusion and mental jedi mind-tricks to rationalize the situation - for both the LBS and the WAS.
Both the LBS and the WAS spend some time living in the 'fog'. The interesting thing is that this 'fog' is diametrically opposed for the LBS and the WAS.
The LBS 'fog' is all about looking at the MR and their spouse with rose-colored glasses and thinking that the MR breakdown was all their fault. If they can just reverse some of their faults quickly, or do more around the house, or spend more time with kids, or pay more attention to their spouse, the WAS will change their mind or come back. In this 'fog', the LBS can't see clearly that they were not the only one responsible for the MR breakdown, and that they were also unhappy with some things in the MR. But, in the LBS 'fog' all of this is obscured and the LBS tries to grab on to any crumbs or shreds of life from the WAS to restore the MR. Once this fog slowly starts to clear and the LBS can see that they are worthy of love, respect, and can see the MR in a more objective light. They also realize that they were unhappy and that their needs weren't being met either. As soon as this 'fog' clears, the LBS is able to take charge of their life, have more control, and realize that they will not go back into the old MR again.
On the opposing side:
The WAS 'fog' is projecting most of the blame on the LBS and rewriting MR history. During this time they can hold anger, resentment, rage etc towards the LBS. The mindset hinders their ability to take responsibility for their contributions to the breakdown of the MR and that their unhappiness is not the sole result of the actions of the LBS. Once their 'fog' starts clearing, they can see more objectively about the MR and realize their contributions to its breakdown. Whether they want to do something about that is a different story, but until this 'fog' clears, they are really hindered in seeing what they brought to the table as well. Sandi has written extensively about the WW mindset, which every LBS should read as well.
A more simpler way to describe the difference in the 'fog' is that the LBS 'internalizes' the faults and the WAS 'externalizes' the faults. I know this may sound overly simplistic and it isn't always fully true, but it is a start to at least unpacking the feelings and thoughts that accompany the 'fog' mindset.
I apologize if I have misrepresented the concept as someone else understands it. I am just sharing what I thought was very useful insight for me about the 'fog' mindset as this is all consuming in the early stages after BD.
