In a depressing new study—about an already sad topic—oncologists Dr. Marc Chamberlain and Dr. Michael J. Glantz and their colleagues found that women given a dire health diagnosis were more likely to be abandoned by their (male) mates than in the reverse scenario.

If couples are happy before the diagnosis, it appears that men are more likely to abandon wives who become seriously ill. If couples are already troubled before a partner becomes ill, the finding suggests that women in unhappy marriages are less likely to proceed with a divorce if their husbands become ill.

(Same-sex couples were apparently not a part of the study.)

While this plays into many of our society’s worst stereotypes–and women’s worst fears–about non-committal males, perhaps being aware of this research ahead of time will help doctors help couples facing a grim diagnosis and long treatment. Who knows? Maybe men and women who are more conscious of the marriage-challenging stress that lies ahead may be better prepared to deal with it when it happens.
