Nicely done! Although we're seeing things through a keyhole, it certainly seems like having the EA in the open has taken a load off for your W. Maybe it's easier for her to approach you when she has less to hide, and easier for her to talk when she doesn't have to worry about divulging something by mistake?
If you view her overtures as a good sign, that's great! A word of advice, in both cases it seems like she interrupted you. When that happens, stop what you're doing and give her your attention, that might be another 180 for you.
