Single and pretty fine about it New York City

I've been single for a really long time and I mostly enjoy it! I don't know why I haven't met a lot of people that make me want to commit and I'm scared my standards are too high or I'm not meeting the right people for some reason. I mean, I sleep with people when I want to, but when it comes to taking things further emotionally I have a really hard time not freaking out and running for the hills. Emotionally intimacy scares the shit out of me! Does anyone else have this problem?!
