I don't have much to say on this since I wasn't in the military long, wasn't married while I was, no kids at the time, etc. I think the term is Peer Pressure, when you see the people around you cheating and bragging about it, and you see it long enough, either you'll feel dumb and transfer, or follow the herd, basic peer pressure. We have all encountered it, be it the way we dress, if we have premarital sex, the peer pressure to get married and have children, be a SAHM/WAHM/Career mom.
Blame the guy and his peers, they are equally to blame. When you marry military personal, you marry the military. I think everyone has made great points here.
I personally think it's harder to stay at home while the spouse works since there is less adult contact, you have to be a full out self starter, cleaning up messes you didn't make and again, very little adult contact. I personally miss working outside of the home. I love my kids, I love my parents, but I miss having friends at work.
Infidelity sucks, been there, done that, never going back. Difference is, my ex didn't have pressure to cheat, he just did, and then again and again, 5 women total, one of them my "best friends" that I don't talk to anymore for obvious reasons. My cross to bear i guess.
