These days, traveling is an essential part of most jobs (in the private sector). Often husband's travel and in case of working women, they too are required to travel. This is causing a lot of stress in relationships. For short or some times long durations, one of the spouse has to stay alone and cope. Things become more difficult if there are children.

Such frequent short/log travels and absence of one of the spouse also brings in a slackness in the relationship.
