Ugh. We can do better than this. Researchers at the University of Michigan looked through 20 years of data on 2,717 married couples and found that 31 percent of marriages involving at least one sick partner end in divorce; and worse, the risk of separation for older couples was higher when the wife, not the husband was ill. Not sure if this is cosmic justice, but men were more likely than women to get sick. This Time magazine article cites another study that suggests that 75% of couples dealing with chronic disease end in divorce. The article goes on to talk about why this may be and even suggests that marital therapy might not be a bad idea as part of the treatment when going through such an ordeal.
