Tried to read the past comments. Just trying to throw in my two cents - for what its worth. She should know you don't want the divorce, so telling her over and over won't make a difference - she already knows. At least from what I could tell in your thread. Definitely need to show confidence. I would say to test the waters now and again - not about R. But try something other than finances. Don't go overboard and barrage her - but just a simple message after being dark a while and watch the reaction. Don't do anything with pressure on her, taliking about R, and don't make it about you. (If you make it about you then she will think you are just trying to convince her how great a guy you are and what she is missing.) If she works, maybe just ask how her job is going and leave it at that. Wait and watch.
Does DB work? Dunno, I'm still working on the process myself. But it has certainly been the best advice I've seen.
