Many have expressed concerns about Andrew and his outright cold treatment of his wife. I do not believe that it is right to hate your wife, however, I don't think that Tolstoy wants the reader to focus on this aspect of Andrew's characterization. I feel as though, especially given the time period, that this characteristic is included in the novel to humanize Andrew a bit. Tolstoy did not want to create amazing heroes who can do no wrong; he wanted depth and conflict for his characters, as many great novelists do. In 1805, marriage was a tool to bring wealth and status to a family, as well as continue on the family name, and rarely anything more. Theoretically, you could look at Lise as Andrew's business partner. It would make Andrew more likable in this era if his relationship with his wife was described in this way. No one would judge a man for acting cold or rather business like with a business partner that he had little choice in choosing. No one would criticize his actions if he disliked his cubicle mate. The understanding of marriage in the day is critical to promote to modern day readers, so that it is easily understood that Andrew's treatment of his wife is not to make him seem like a bad person, but almost to make him more relatable and likable for the readers of Tolstoy's era.
The idea of Andrew's treatment of his wife never bothered me, partially due to the history, and partially because it intrigued me into thinking that there must be a deeper characterization waiting below the depths of Andrew's 'public' face. I'm constantly looking for clues as to why else Tolstoy might have included this detail. I'm hoping as I read on that I will find a dynamic back story to explain Andrew's behavior. Even if I don't, I'm sure Tolstoy will tie up all the loose ends for me anyway. I'm looking forward to the moment where I see a more pressured, deeper side of Andrew.
