I like Labug's suggestion. Then go with a plan to listen to what she has to say. Don't give away much on your side and definitely meet with a lawyer first so you know where you stand. Listen and finish by saying "you've given me lots to think about, I'll get back to you". Oh, and the other line (don't wang this, won't stand in your way).
Reminds me of Maybell's recent experience. Although it must have been hard to sit through, some clarity seemed to come from it. Maybell - please shout out if I've made an incorrect statement there.
Another reason: you're W says she'd rather meet to discuss. Here's an opportunity to show that you hear that need. I don't think it's wet noodle if you bend on this one. It's an important issue and email ain't going to cut it IMHO.
But I'm no vet, so....
