You can never go back, really. Things always change, and when you are gone a long time and return, things are rarely ever the same as you remember them. I hope if DH and I ever move to the USA (he says he would like to when he retires) we move to a different place than where I am from, in order to make a new start together. Besides, after living this country life for a while, I imagine being in the city again would be overwhelming....
