Don't read too much into the daily contact with W. It doesn't necessarily mean her feelings for you are changing.
I also feel the no contact thing is over prescribed here. Notice in DR Michele promotes it as just one of the many techniques to try, and a "Last Resort Technique" at that. It's not something that everyone must do right off the bat.
To me, NC smacks too much as "teach 'em a lesson". Sure, you don't want to pursue her, but that doesn't mean you have to cut off contact. It's a dance, and you're letting her lead for now. If she's contacting you, don't fight it, go with it.
The end goal is to have a great connection with your wife, so I see contact as a good thing.
BTW, what's LTTCOI?
M: A really long time. Crisis: 5 years. She's still worth it.
