From what I have observed on the board, whenever the term "temperature checking" is used, it is referring to the WS checking the LBS emotional response to determine if they are still Plan B. This usually comes through some form of manipulation by the WS.
Not that I have read every post on the board, but it is rare to see anyone refer to the LBS as making the temp checking. As Another Stander pointed out, it is not an action the LBS should even consider. Temp checks by a LBS causes them to appear as having low self-confidence. Since healthy self-confidence ranks high on the list of most attractive traits in men and women.......it only makes good sense that the LBS should not succumb to checking the emotional pulse of the one who wants to end the M.
When temp checks come from the WS, they are a form of manipulation. When temp checks come from the LBS, they are a form of pursuit.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
