Does Angel grow or evolve over the course of Taylor's novel?

Elizabeth Taylor's novel Angel (1957) is one of the many, many English novels of the 20th century (even the 21st!) to build part of most of its plot around events of the first World War, whether in battle or on the home front. In ET's case, however, the war is largely offstage altogether: Angel's husband, the unfaithful and egocentric would-be artist Esme, volunteers to join the forces (in part to get away from his cold marriage and miserable life in the remote English countryside); we see no direct depiction of the war, though we catch a glimpse of Esme on home leave having lunch with an attractive young woman - Angel doesn't know why he never gets home leave as so many others do, and now we - and his sister/Angel's friend Nora - know why. We have a quick jump to after the war, w/ Esme now home and wounded, having lost the lower half of a leg. Predictably he morose and miserable and a profligate, blowing through a wad of money at the races and the card tables and slithering up to Angel asking if she can pay off his debts. She, however, has no ready cash - sunk it all into renovating their manor house - but she secludes herself in her bedroom for weeks, maybe months, to write a novel. Why she puts up w/ Esme is almost beyond belief but does show once again Angel's strange dependence on the only man she ever loved, if she even loved him; she seems to have little sense in her life of happiness and partnership. At the end of section 4 (of 6, though the last 2 are much shorter than the others) Esme shoots himself to death - with a rifle, it seems, which is almost impossible to do, but never mind, these are like the wayward facts that ET ascribes to Angel's writing, so ET can get away w/ some herself as well (or maybe I'm wrong on this point, wouldn't be the first time). All told, this novel continues to be a good read a sorrowful (if unsympathetic) portrait of a talented yet unlikable woman; she doesn't have the depth of a Wharton or James character, and the last sections will show whether she learns anything from her experiences, whether she grows, gains insight, or whether she dies as lonely and offensive as she has been throughout.
