I recommend pulling back a bit tonight. Create distance. Grab S and go to park and feed the ducks (or something like that).
Because?
Whenever there is a moment that causes positive emotions for the LBH, the WAW will often pull back the following day b/c she doesn't want him to think they are reconciling just b/c they had a moment. She doesn't want him making more of it than it really is.........so she'll pull back to remind him nothing has changed.
I think R2C was telling you to pull back a little, to show that you aren't phased by the playful actions from your W, or that you enjoyed a concert together. It is a way to protect your own emotions, instead of "watching" her to see how she's going to act.
You may experience these type of emotions several times. It seems whenever the LBH has a day where his emotions run high (and especially if he feels a boost of hope), invariably, it will be followed by a period of feeling "down". It doesn't mean anything expect that it's emotions, and you have to keep them balanced as much as possible.
Instead of trying to analyze what all this means, just follow R2C's advice and get busy. Remember, pulling back does not mean to act cold, sullen, mad. You just don't hoover over her, sit and watch her, etc. You GAL.
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!
