I'm over 30 and I've been living in NYC for 13 years. I've learned a few things.... People here are concerned about making money and getting ahead, and then they leave. They're not always looking for love. Is not impossible, but it's rare to find. There are more women than men here so the men can afford to be complete jerks. They will always look for the next best girl. There is always going to be another girl who will take their crap, take less than you will, will allow themselves to be taken advantage of. Men stay single here because they can afford to. There are tons of guys in their 40s who are successful and single and chasing 22 year old tail.
My advice? Keep your options wide open. Don't get sucked into the city vibe. Majority of people in the tri state are rude, self absorbed, fast, competitive. I've never experienced rudeness of this magnitude in any other state, especially from men.
Get online. Go out and do group activities and hopefully you will meet people who share your mindset. Um, keep your options open geographically.... I travel a lot and I've met really nice men in other states. Men don't even buy women drinks in NYC anymore. In any other part of the country, women have the upper hand in dating.
If you can make it here, it's true, you can make it anywhere. And that is a good thing to realize!
