I didn't recall that Mrs. Cemar was different. That does rather change the dynamic. My H was consistently LD right from the start of our relationship (he would come over and sleep with me and not have sex when we were dating) so that developing LD as the relationship progresses problem didn't really apply. I guess the answer to regaining lost GGG would probably involve changing the dynamic of the relationship in such a way that the conditions of initial courtship were once more in place psychologically. The only way to do that IMO is to simultaneously start courting your wife but also make it clear that the continuation of the relationship is not inevitable under present circumstances.
