- family nearby
- friends nearby
- as a consequence of the above two: support network is in manhattan
- enjoying the local parks/scene/etc
I grew up in <midwest plains city> and then moved to <rival midwest plains city> for a long while after college, eventually moving back to my home city because that's where all my family was.
It was a hard move in both directions and all things considered, I didn't even move that far. In city B, I missed my family and the stuff there was to do in city A. But after moving back, I now miss a lot of the things we did in B. And I don't even consider myself to be someone to particularly likes leaving my house!
Advice that tells people to "just move" is pretty shortsighted, I think. I really doubt OP moved to manhattan just to be able to be snooty about living in an expensive city, or something, which is honestly how I kind of read these kinds of advice - though it's probably not a very charitable read of your argument, for which I apologize.
