The silence of Ferrante - something allegorical in TheDays of Abandonment?

Started the short novel The Days of Abandonment by the Italian myster7-woman(?) Elena Ferrante - the author who has never given interviews (maybe something online once though) or made any public appearances or even identified herself (or himself? - certainly seems to be a female writer). I admire Ferrante's honesty, her unstinting belief that the work exists in and by itself and that the identity, personality, image, and personal history of the novelist are not relevant and in fact are potentially distractions or deterrents - yet of course the irony is that Ferrante has received more attention for her lack of identity than she ever would have had she gone the standard author's route and posed for photos that would have been ignored. Anyway, the book - is at least initially (50 pages in, but I suspect some plot twists and maybe even some postmodern contortions may come) a woman's deeply embittered account of her life upon being abandoned suddenly and inexplicably by her husband of 15 years. The narrator is 38, with two young kids, in first paragraph she exits her husband - he says he's leaving and walks out. The next 49 pages are extremely caustic, and with good reason - her husband is a complete prick, tells her nothing about where he is, disappears for 38 days (something significant about that? some religious parable working here?); she hears from friends that of course he's with a new woman, but a wall of protection seems to exist around him and his new life, for no apparent reason; the narrator indulges in sad fantasies about the current sex life of her husband, and she makes a few pathetic attempts to win him back, to no avail. The writing is very powerful, and I can see how this book would become almost anthemic for many women who have experienced the same kind of cruel desertion; but I'm hoping that some kind of plot does begin to take shape - there are indications that the narrator may build a relationship herself with an older (53) musician who lives in her building. There also seem to be some allegorical themes developing: the abandonment may be a spiritual and religious abandonment and well as a marital one; there are also many references to the gradual decay of her household, the increasing disorder, an invasion of ants and of a lizard - are these elments allegorical as well? Do they echo or reprise the 10 plagues on Egypt? Well, Ferrante, for one, isn't saying.
