I've found that though DB/DR puts names to certain techniques, sometimes people use them intuitively without knowing they're "acting as-if", "doing a 180", or whatever.
I started DBing long before I ever heard of it.
Your W seems to have started DBing a couple of months ago.
Part of the DB arsenal is going dark. We all must go dark to some degree as we work our way through our feelings.
It would do your R no good at all for you to hear about her misgivings as she works her way closer to you. So, you have to stand on the sidelines and watch her emotional roller coaster.
Just love her KAW. That's all you can do right now.
