Have to agree with the majority of posters here. I have been a navy wife for 10 years. DH has been on boats, sometimes away for months at a time, and has also been based at the absolute other end of the country for a year. It never even crossed my mind to follow him about the place!! I had my own job and then my babies. Yes, sometimes it's not easy to be apart- especially when I was pregnant, or at Christmas. He even missed dd2's christening, but that, to me, is life as a navy wife. The kids, I feel, adjust better to not seeing their dad for some periods- we try to do some weekends/ occasional flying visit- than they would to do without either of us! To me (and this is just MY opinion!), when the dad is not in a 9-5 home-every-night job, the kids need the stability of their mum even more. DH and I are adults- we can manage without each other, and I'm confident enough in our relationship to know that it can withstand the seperation.
I understand that different people feel differently, but I don't get this if-you-are-military-family-it's-a-necessity. Yeah, if you are BOTH military on different postings, it is! Otherwise it is a choice. DH can go all over the world, and my dc will stay at their local primary and with me. OK, they do miss their dad, but I know loads of fathers who work such long hours that they hardly see their kids anyway- it's not so different. We still feel like a family.
