I once read a quote by a LD wife who later in life re-discovered her drive only to find out that her husband no longer had his . . . "I taught him well".
While I would certainly enjoy it if my wife acted like you are now, I would certainly not begin initiating it just becuase she seems to be in a groove. Old hurts are sometimes hard to forget. You're going to have to give him a while. After all, whose to say that he isn't thinking that his advances were what pushed you away in the first place? If he had stopped initiating some time back and now you suddenly seem to be a changed woman might he not think that his backing off caused the change? If so, why would he do a 180 now that things are clicking again?
