From what I have seen from other forums (marriagebuilders and survivinginfidelity) it is totally normal for WS to get to a point where they stop trying to communicate with NC. Most of the time it is temporary.
Think about it--she is ticked off about your NC. Totally not expecting that of you. She is immersing herself with OM. Totally to be expected, NC or not, but NC makes it easier. This is where they get their emotional needs completely met but OP but after awhile, they realize that OP can't give them what they had with you.
Also, although it FEELS like it has been forever, you have been NC what..4 weeks? Maybe 5? So in the big picture, this is a pretty short time.
I bet you 1000000 pounds that she will contact you again! Seriously! And as for people telling you to move on and that she has...been there done that. These same friends have told me recently that they now think there is hope and that they just want me to be happy no matter what. Think about what DR says- our friends and family just want us to stop hurting.
So continue with NC which you are doing "famously well" and EXPECT this kind of reaction from her. It is soooo normal! (Just like DBD's WH is acting which seems to be common as well!)
