I really don't think it's all that complicated. She's confused and having second (and third, and fourth, and . . . ) thoughts, and has shown this to you repeatedly, and all she gets from you is this sorta sick "well, too bad, toots" game.
"Twist the knife a little?" Look, I COMPLETELY understand the power rush you're getting from having the tables turned on her, but I don't think it's going to be productive to your future relationship with her, in whatever role it takes. Either you're still DBing and trying to save your marriage, in which case you're blowing all of the openings, or you're moving on, in which case you might as well just take the high road and stop torturing her this way.
Just my opinion. I do agree in general that "Limbo Sucks," and could see why you wouldn't want to drag this out.
