Oh, and I don't think it's indifference you're describing, but detachment. It sounds like your W is realizing that, in your mind, you're ready to move on without her if you have to. That might be what's pulling her back in.
The old, "I want what I can't have/fear losing" thinking. Just a thought, but there may be an element of that in her movements back to you.
Not sure that makes total sense, but, there you go
