Give it time. One thing I have noticed in most sitches that have gone a similar route as yours is that with time, your H will slowly realise exactly what he has done, and that the grass wasn't as green on the other side as he had hoped. But you may choose not to be there when he does realise this.
I know people all say that the success rate is pretty low on this site, but I often wonder if the success rate is low due to the LBS calling it quits and moving on before giving the WAS an opportunity to come back?
