A lot of choices made during marriage are dependent on both people. One spouse will take a job that involves travel means the other cannot if they have a child.

A lot of choices made during marriage are dependent on both people. One spouse will take a job that involves travel means the other cannot if they have a child. Or one spouse could be stay-at-home, while the other works (once again, generally for children). When choices are made for the benefit of the couple, then both members should face the results of those choices.
