Mike,
I'm just guessing, but W is probably afrain of slipping back into more of the same. Patience is the key here. Let W hold the control key on this issue. If you push her, it will be a backslide for sure.

Focus on how you can put W worry at ease. This does not include pumping her with OR conversations. I know it's hard but find a little piece of happiness right now. I'll bet W can detect your unhappy feelings and they translate into stress and pressure for her.

Remember, patience!
