Hmmm.... To start, don't make too much of it. I think that she was saying that she wasnt' even sure she'd call it a "date". But that at least to some degree it would look like a date.
More interesting, I think, is that she still wants to keep the peace. That doesn't sound like someone that is done, to me.
Ok, the other interesting thing. She asked her friend not to tell you, but her friend did. So, make sure you don't trust this friend with anything you don't want W to know, either! There's a good chance it works both ways.
