Archer - The nice part about DBing is that it really is all about the LBS. The strategies and steps and everything are things you should be doing for yourself no matter what the S is doing. By trusting in the process, you'll come out the other side as the person you want to be. Ideally, that's soneone your W wants to be with.
The reason I say that is that at any time, you can decide that you don't want to be M anymore. Almost everyone's S has done things to seriously damage their Rs. The question every single person has to ask themselves all the time is whether their goal is to be married to their S. If that answer is "No", it's pretty easy to proceed from there. But it's a decision we all have to constantly re-evaluate.
