AAaaaaaaaannnnnnnnnnnnnnnnnnnnnnndddd.... back to the topic at hand...
There are a couple of big reasons divorce rates are high in the airline career field, in my opinion....
1) Time apart is obviously a factor. However, in today's world of cell phones with unlimited minutes, it's much easier to keep COMMUNICATING, even when you are apart. When my wife and I were dating, I was in a situation where I was only able to see her on weekends (hmmm... much like now, except now I only DON'T see her on weekends!
. We spent a lot of time them on the phone. We were best friends before we got romantically inclined, and we kept getting closer even afterwards because we spent a lot of time talking--it was great, and it has served us well ever since.
2) The temptation factor is very high, especially for the flying spouse. Face it... we're out for days at a time, and eventually you are going to be on a crew with a relationship "shark"-- someone just out cruising for contact. It might be a "toucher," or one who laughs at every joke you make, or just someone who thinks you're fun, but it's obvious they are trying to "make contact." It's important to recognize these folks and avoid (politely, if possible) falling into their trap. (Yes, I know this happens in other career fields, too... aviation just seems to have a higher percentage)
3) Being apart leads to another problem--while you are gone, she will establish her "routine" of how things get done around the house (this is MUCH more of a factor if you have kids). When you come back, you (unintentionally) upset the applecart, and it takes some readjustment. The longer your trips are, the bigger factor this is. When I was on 90-day deployments with the AF, it was HUGE. Now it's much less of a factor.
There are some
good things about the life, though. In our case, being apart has actually been good for us! My wife and I are doing better now (relationally) than we have in years. First, I'm doing something I really enjoy (the AF and I kind of "grew apart" my last few years in). By being gone a few days then coming back, she has the opportunity to "miss me a little" every week--she looks forward to me getting home (hey... THERE'S a plus!)
Like others have said, do what you love, put your marriage first, and you'll be fine. If you don't, and you don't, well... it won't matter WHAT career you're in.
Best of luck!
