I am far from most of my friends and live in a city for work reasons. There are more activities and everything is a lot more accessible. Definitely more promise in the air. That said, I am living alone and feel it. It's not healthy.
I do want to be nearer friends and (some) family but ironically I think there are fewer relationship opportunities back in the sticks, plus there are attitudes and people in my home town I really don't miss.
I agree with your conclusion - but when younger and single it is difficult to know exactly what to do. Being single being a big problem, and the day to day work from home isolation the other.
