I want to toss in something else here, too... SS, I understand what you are saying, for sure... I think your 2 case proposition is accurate...
Sometimes when we're looking for an answer, we might loose sight of what the question truly is...
I know OP says this a lot, probably others as well... "It is great to stand, just make sure that it's not 'still'..."...
Thundarr, true enough, there's something going on in each individuals psyche that we all go through in order to make decisions that "work for us"... while all decisions and choices made by an individual are ABOUT that individual, there are... extraneous affects of those choices and we may or may not forget that the input and feedback of others who are will be affected by our choices, should be taken into consideration...
Such as our choice to stand... and for how long...
For example, if a spouse is not MLC... does a LBS simply "give up" after... say... one year post D...
In other cases, like Thundarr expresses... how much weight does one give to obvious lying...? Whether that be blatant lying or lying by omission or any other form... We have a tendency, not sure rightly or wrongly, to want to believe that when our spouse could be so disrespectful, that we want to excuse it by suggesting an irrational mind of MLC... even though we understand that, MLC or not, poor choices are poor choices and... we then need to choose, as the betrayed LBS, our ability to forgive...
What do we trust? How do we trust?
Like the joke about the litmus test above, a WAS would believe we hate them and the MLC might think we're pursuing... our choice to accept a truth of a WAS that they want out... or misunderstanding and believing the claim of the MLCer that they want out...
We choose to stand, in the face of our WAS or MLCer "executive decisions"... but do we stand in denial... the "fool" as it were... or alternatively, do we exit on false information...?
