It seems to me you have a chance here to just back way off, without giving up at all. YOu are D, you can go on being nice to her periodically, without pressing for anything else at all. IMO, letting her take the lead totally is your only choice.
Not sure I get this. Are u saying to go a little dark and then pursue a little, like ask her out on date. Isn't she the one that has to be in the lead?
