How long of being dark before I should expect to hear from WW in a temp check way
There's no good answer to that unfortunately. If you were pursuing like crazy for a long time, then WW will be afraid you'll instantly start pursuing again the moment she reaches out to you, so in that context it could take quite a while for her to believe you're safe to reach out to.
If there's an active affair, reaching out to you might trigger feelings of guilt she wants to avoid, so she may not reach out to you until her affair is over and she's feeling lonely.
Point is, its all in her head and there's no way to predict that. Best way to look at it is that "a watched pot never boils", so if you don't expect her to reach out you won't be disappointed if she doesn't.
