Have to agree here. My anecdotal experience? Had a bunch of friends after college, all move to SF for work. Three years later, they've ALL moved across the country to find work in less expensive areas, living in Suburbs.
Haha, this is kind of my plan. Just finished grad school and will probably end up in SF or somewhere similar for a while. But my girlfriend doesn't like big cities and wants kids in a few years, so I imagine we'll move back at that point. Unfortunately, at a personal level, I find cities much more entertaining and enjoyable to live in than suburbs (having grown up in the suburbs). But maybe that's just me.
Your situation is, more or less, exactly like mine lol. Right down to the fiance not liking cities, but me liking them very much. Quite a pickle to be in, since I know it means we'll end up in the burb's eventually and I'll likely have a midlife crisis.
Haha. It is indeed a pickle. Both mine and my girlfriend's families live in the South, which means eventually the only (world) city I'll be near is Atlanta, which isn't exactly a tech-haven at the moment.
