I'm gay, live in JC with my spouse, and most of my friends live in Manhattan. I don't think this is a jersey city problem though, it's just that I met most of my friends in grad school in NYC and it's hard to make friends as an adult! Personally, I still find it worth it. I live in the heights, so I can live in a three bedroom apartment with backyard access for the price of a one bedroom on the upper west side, where most of my friends live.
