There have been a couple of success stories I have seen, but those people no longer come here, or rarely visit anymore....cuz they don't need to. But I believe those successes were prompted by the person (as I recall generally the HD) doing the things many of us have mentioned that eventually did lead to the other person "getting it". Very often though the R morphs into something mutually satisfactory that has a much better EC and isn't as focused on "sex" as the HD partner intially wanted it to be. Yes, the sex is there....but probably not at the frequency the HD person initially wanted, but the EC is much better...which makes for a better R. Now, if that's not your idea of success then I don't think I could say I've seen many successes....but for me, that would be a HUGE SUCCESS!
But what you said is that you want instances where they do have a success where one of the spouses got the ball rolling....The NOP's. I believe Mr.NOP's (correct me if I'm wrong guys) got the ball rolling....then eventually with work, with communication, with change on Mr.Nop's part...Mrs.Nop's eventually started making changes as well. You can see for yourself what a wonderful R they now share.
But as you said yourself....one person has to get the ball rolling. Isn't it our responsibility as the HD spouse with the issue (afterall the other S doesn't think it's an issue) to get that ball rolling, in whatever manner it takes, if we value our M's as so many of us do?
