It sounds like it's a case of the grass being greener on the other side. For a while, I didn't like living in urban Cleveland--I missed the greenery (even if it was just manicured lawns and whatnot), the space, and the relative quiet of the suburbs (as well as the fact that I had access to bike trails and roads that aren't full of potholes). Now that I'm back in said suburbs, and will be moving to one in a different city, I miss being able to walk everywhere, the unique coffeeshops, yeah... Won't complain about the cycling or the lack of drunk people puking on the sidewalk outside my window, but still...
