Thanks TTD180 and 2old. As I said, I am pretty comfortable with my own answers, which by the way are the same as both of yours. Just putting these questions out there.
TTD180: Still no contact with the W. We haven't seen each other, talked or messaged since the discussion about the mortgages back in July. Apart from one silly text I sent a few weeks ago - no reply to that anyway. With regards to Q1. She will know the address, it is our house we own. Me telling her won't make a difference to how I feel. The difference would have been if she asked, rather than being told. Her reaction: again it depends on whether she is in a relationship. But I would expect that her reaction would be great, I don't have to see him (not that she does) and more than likely she would be able to focus on being a single person without much history that she would need to explain to people.
2old: I expect the same kind of response from the W. If I contact her, she will start to think again about the solicitor. My W is definitely in her own world and presumably quite happy also without me.
