sounds to me you might be a coppers wife

as for moving to small towns cant say I have moved to small towns but have moved from Melbourne/Sydney to Darwin Cairns and soon to be moving to Mackay from Melb.... now dont get me wrong I know these places arent small but they are regenal towns and compare to Melb and Syd...

we have been back in Melb for 12mths and its just too big I dont find the people friendly at all they all seem very closed off, but when I have lived in Cairns / Darwin ( and I hope Mackay will be the same ) that if you make the effort then if can be wonderful... But just know that it can take sometime for the locals to warm up expacally if they know your DH is in a job where you could move again then they kinda get sick of trying with the new girls...iykwim...

if you know that you could move away again in 3 years if you dont like it, then I would do it, its only 3 years which would mean you could be a sahm and be able to join playgroup and swimming so you will have pleanty of chance to make new and maybe long life friends...
