Natus, it has been awhile since I've been on your sitch, so I had to go back and read quite a few pages, but I will say doodler's fascination of your smiley face girl made for easy reading.
Anyway, I'm glad to hear about the pending NC with OM, and your W's wavering between separation and then MC, it shows that she doesn't know what she wants which means she hasn't confirmed she wants to separate. Anyway, I believe if you give her space (she's probably gonna have a tough time when NC goes into effect) while she settles in to her new reality, it will go a long way. It's going to be tough, but be the lighthouse, don't ask how/what she's feeling, just be a confident/steady person that she can use to lean on when/if she needs to talk. Her worlds gonna be rocking, if your rocking too, it will be too much for her.
I might suggest that you read my previous thread, it may help to see the feelings/questions that I struggled with when starting to piece. I still struggle with many of the questions, but I will say every day seems to be getting better (especially the last few mornings :), so as you struggle with if this is really what you want, I would urge you to at least wait awhile until you get to some of the good/fun times before deciding.
I would also suggest LIM's thread, as he is also piecing. I know your not there yet, but if your wife commits to working on R, things can start happening pretty fast. One of the common questions/concerns is "did I let her back to soon?", you may want to consider what you would need from her before you agree to work on R. It is pretty scary to be piecing and wonder if the WS really understood the effects of their actions and if they really, truly want to commit to the MR, or if they are just doing it because it's the right thing to do.
