Thanks 2TH, I will look up that thread - hopefully it isn't too hard to find...

Meanwhile, W told a friend yesterday that "If he had come to me like this a year ago, we wouldn't be in this mess."
Makes me think I might be on the right track now, but she's still just too angry to accept anything I do.
Maybe I'm reading more into that than I should.
In any case, it sounds like LRT + 180s + consistency + patience are good. Keeps me hopeful anyway.
