Since there is no other reason for contact, your W appears to be finding reasons to not have to be in your presence...
While I don't necessarily disagree with the likelyhood there is someone who is "coaching" her on some stuff... who that might be is only a guess...
So while someone could suggest you go full NC, she's already initiated NC, except for stuff relating to financials and dissolution...
Not sure, but since she figured out the cc thing... you COULD have been NC on that. And dissolution can be completely through the Ls.
In the other hand... you obviously have common friends... small community, maybe...
While it's NOT a tactic... you may want to REALLY step up your GAL. Dress as well as is reasonable when you go out... kick it up a notch, Emeril... a bit of cologne, maybe a little blue on the face (chicks dig that, sometimes)... be happy, light steps walking in public, lot's of "Hey! How ya doin'" kind of stuff when you see people on the street...
Get out to shows, invite friends, female friends... to go to public places like coffee shops and stuff...
The ONLY goal here is to GAL and enjoy yourself and take your mind of the cr@p in your life...
but MAYBE... a secondary effect might be that your W will hear about this... and become curious... and start contacting you to find out what's going on...
but it's NOT a tactic to win her back... your just becoming a REAL CATCH that only a FOOL would leave...
