How is being away from home for 15-17 days a month as a pilot any harder on a relationship than a workaholic spouse who works 70 hrs a week in a traditional job?
While the workaholic might technically be home every night, is he (or she) REALLY able to give the other his/her undivided attention and affection when he isn't working?
While the pilot might be away from home a lot of the time, he is ALSO home a lot, and every minute of that time spent at home on the remaining 13-15 days each month (more if one has decent seniority), can be used 110% for focusing on and maintaining a healthy relationship, since pilots are truly OFF, on their days off.
Just have to ask
