It seems a few posters on this thread have had an empathy rain check. I don't watch Gareth Malone because I am not fussed on him, but I am a military wife and now a military mum.
In my everyday life, I don't describe myself as a military wife, I'm Mrs X, I don't introduce myself by saying "hi, I'm Fairy, I'm a military wife!"
It has never, ever been suggested by anyone that miltary wives, husbands or partners love their spouse or partner more than anyone else, but they do have a lot of challenges along the way. Most people will never know the feeling of seeing their loved one walk down the path with their bags, knowing that that could be the last time you ever see them. It is particularly hard having small children crying for daddy night after night after night. Thinking about those times can make me cry instantly. It is not acting, it is reality.
Last Christmas was shit, DH was away. Next Christmas it looks incredibly likely DS1 will be away. It's their jobs and we do get on with it, because that is our life. We don't moan, we carry on. DH was recently promoted, I didn't think "great" I thought "oh fuck" , because it means signing on for extra service and he'll be back in the pot for deployments.
If you don't like the program, fine turn it off, but don't sneer and take the piss out of women who are doing a difficult task of keeping a family together whilst worrying about whether their loved one will return alive or uninjured.
