When I was reading through the passage in DR about the LRT, I noticed it didn't mention a time frame within which it would show its results, if any. Things take as long as things take. For some, it's less time than you, for others, much longer.
Your focus is apparent on the OM and on your perception of your WAW. Yet also minimize your WAW's perception of what was wrong in the marriage. I really do believe that these negative type of focuses influence how we act in our DBing, and sabotage or undermine our efforts unknowingly. In a way, it's just like a WAS who is in a EA with someone, and by being in that EA, is not emotionally available to working on the primary relationship, and so any efforts made on the WAS's part to work on the primary relationship is automatically doomed although the WAS believes that he has "given it his all" and "tried everything", when in fact, that's not really the case. So a LBS, who believes they've been DBing 100% but still having thoughts and feelings of a darker nature can't truly be DBing 100%, because if they were, they'd be helping themselves out of that mind set first of all.
My suggestion, Jabez, is to work more on thought control, change your perspectives, and give it more time. The OM being in the picture does make it more difficult to see progress, but progress can be attained despite the presence of OP.
I think the way you're going about "Dispelling the apathy" reality, not myth, it's a reality to your WAW, OK? is on target. In your convos with her, keep notes if you need to afterwards, of things she mentioned coming up in her life with which you can follow up later in time. It also makes good practice for sharpening listening skills. The opposite of apathy is caring and empathy... so work on becoming a more caring and empathic person, not just to her, but to the people and the world around you. Developing and growing those parts of you will, just as in the above examples given, become evident as they influence other things about you, and WAW will notice in time.
