Any takers on breaking that one down?

I see possibly as a an effort to comfort S10's fears and not address the issue completely with him. If this is the case I believe she is setting up a bit of resentment and distrust from him if D is in the future. She is deluding him, and protecting him (not that it is bad). IMO, Best to have left it at mommy and daddy love you and always will. This is not of your doing and do not think that it is.

OR

She is making a clear effort to shake me up and has taken D off table but will not let me know or is in the process of doing so. Making the point very clear that my actions are causing her issues.

In reality it does not matter b/c it is speculation.

If it is speculation, which it IS, why focus on it?! Your W probably really Doesn't know what she wants. And Definitely don't go thru your S to get more information. If he is feeling good right now, then just let him. Don't burst his bubble.
To the contrary of pursuit, any detachment I give or space I give is deemed moppy and sulking.
If I opt to take kids out without her...sulking and trying to prove a point.
If I choose to sit and watch TV...sulking and moppy
If I choose to check emails from work on computer in basement...pouting and moppy

I don't understand this. Did she come right out and SAY when you do those things you are moppy/pouting/sulking? Or is this all your interpretation? And why would this be the case at all? ARE you sulking when you do those things?
That's the whole point of really detaching vs acting like you are detaching. Clearly she thinks it's all an act or you wouldn't report those actions as being associated with a moppy attitude.
