I agree with what the other poster said. But only tell her this if she asks you. Don't bring it up on your own.
I think one of the main keys to DB is that you start to make the WAS feel like they are the LBS. And the only way to do this is with your actions.
You start moving on. You start living your life without them and enjoying it. I think WAS's can feel it when they sense the LBS moving on. The LBS gives off a different energy, and they have a glow about them.
That's why DB always pushes GAL and "acting as if". You have to start making the WAS feel you losing interest (and not in a spiteful angry way). But in a peaceful, loving way.
That's why I keep telling you to stop doing things with her. If she asks to hang out, tell her you have plans (and act excited about the plans when you tell her).
She might resist and act angry and start talking divorce. It's all fluff. She will try to manipulate you to get you connected emotionally because it soothes her. She can leave you and venture out on her own and have the comfort of knowing you will be waiting if she decides to change her mind.
You do not want her to feel comfortable right now.
You HAVE to get over your fear of losing her before you can get her back.
