Well, someone has to take the opposite view on the cheating issue...
A six-month cruise is like being in a parallel world. Even with email and phones you can get disconnected from your spouse...
and you will be surrounded by a 90% male peer group that is going through the same s**t you are going through...
No matter what you look like, you will get treated like the prom queen. Everyone in the air wing will know your name within a week. Everyone will want to talk to you. Not necessarily to hit on you, but because their wives, girlfriends, etc are 8000 miles away and sometimes you just get tired of talking to just dudes.
Of course, some of them will flirt, and some will blatently hit on you. They have never met your husband, and in the little world that is CVN XX he doesn't really exist in their minds, he is an abstract concept.
Will you cheat? I don't know you, so I can't say. But you will have the opportunity. In my observations more of the women on cruise cheat than the men, and it is because of opportunity. If you want to cheat there will be a choice of partners waiting in line. If a guy wants to cheat he needs to put in a little more effort.
But that's the scenario- it's been 4 months since you've seen your spouse, and he doesn't seem to understand what your going through. Your surrounded by your JO buds, and they do understand you, because they are going through the same stuff as you. It's 2 AM, you're all drunk, and headed back to the "admin" (crash-pad hotel room). Someone, maybe someone from a sister squadron, makes a pass at you:
Would you cheat?
