brkn, you can't control what she does. The more you try, the more you will push her away. But you can control what you do.
Do you really thing that you seeing someone else is going to be helpful? Let's assume that you actually grew to like this other person? What if they actually grew to like you? And then, once you are in a pretty good, growing, relationshp with this other person, WAW decides that she'd like to try? What are you going to do then? It's just a bad idea.
And don't try to use her actions to justify yours. I don't have any problem with you deciding you are "done", now or at any other time. But until you are, you can't play both sides of the fence. That would make you pretty much a WA too, I think.
Stop worrying about what she is doing, who she is talking to. Get your focus on you. You are the one you can make better. You are the one you can control. Asking her for the "least she could do" isn't making you attractive to her. It's closer to begging.
