You'll know by her showing you, not telling you. In my sitch it was weird b/c she did show some things (put ring on, sex) but was mostly just talk. The doing part is where she wasn't getting closer to the MR (she lied to OM instead of breaking up with him). Your W seems more stable than mine.
Just remember to validate feelings and truly listen. Part of listening is asking questions to gain better understanding. If you aren't sure if she's serious then keep validating and listening. Now go reread the validation threads.
It think the DR book has some guidelines on this, I would reread that section too honestly.
