Sorry I'm chiming in a little too late. I hope you went out with W and had a good time. I would have recommended it, but no R talk. If she wants to talk about your M then tell her no R until the A is over. (Sandi's advice - and it works). If she later starts talking about R, ask is A over. If not then say, then there's nothing to talk about.
Yeah could be cake eating. But going out with her and showing you best side can't hurt as long as conversation is kept light. Humour helps too.
