I'm no expert on DB in fact right now I wonder if I am doing it right. Yet my interpretation of it says that DB is about making yourself better so you are irresistible to your partner. To show your partner why they found you so great in the first place. Ultimately you have no control over your partner and their struggles. You can only set yourself as a positive aspect of their life through all the positive changes you can make through 180's and GAL. I don't know your sitch very well, but I understand that some WAS use the marriage as an excuse to justify their situation. Remove that excuse by being your best, and he may find himself having to examine the true reasons behind his problems.
