However, how does that go with NGS, NC, and shocking WW out of a fog?
NGS I think that NGS would be sharing what you would want to be shared with you....and then getting mad when she doesnt reciprocate. Replying something little because you believe it is the right thing to do with no expectations of her replying I think is perfectly helthy. And a good chance to be David2.0.
NC You have kids with this woman and some amount of shared custody. How much NC can you actually do? She asked you a question that I dont believe is particularly offensive or persistent or intrusive. So it's up to you whether or not to answer it. Is she texting you nonstop? Is her communication rude? This is a new thing for her with you having the kids 2 weeks (which I think is QUITE a long time for the kids to be away from either parent). I think it's reasonable to provide a short update halfway through
Shocking WW To me, the biggest shock will come from you BEING David2.0. I dont think "punishing" her by cutting off contact or info about the kids is really a good way to get her to think about 'the new you' and draw her closer. I think a short reply at a convenient time is a great way to portray the man you are becoming. Cool, confident, and busy.
