At what point do I ask her out for coffee or a date? Or do I never do that? Do I wait indefinitely for her to ask me??
In order to keep your attention off pursuing, you need to make up your mind that you will not ask her for a date. The first step in DBing is backing off and stop pursuing. Focus on becoming more involved in life itself. Become more independent of her. Become more interesting and a bit mysterious to her.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
