After having moved to a new large city (boston), I too tried the online thing. However online dating has only ever lead me to shitty dates. The people on there are seemingly only interested in extremely superficial things. For a while it got me pretty down, but then I decided that I wasn't the type of person for that scene.

I met my current girlfriend at a party thrown by a work friend. However if you aren't supposed to get close to people I can see how that would be really difficult. I would suggest looking to see if your city has meet up groups, ones that people join just to get out and do things. You may better find a potential partner in a setting that is not high pressure (like an online setup date). Its nice to be able to get to know someone with out the whole intensity of dating and whether or not to be physical to get in the way. My only other suggestion is to join a club or perhaps an inter-mural sports team. I had a friend who found a pretty good boyfriend from a bowling league.

Keep your chin up and best of luck!
