I met my boyfriend on a dating site. We've been together for two and a half years now and are still going strong (we're together in person now; he moved to where I live around the time we got together).

You know what the key was? My boyfriend didn't approach me looking for a date or a meet-up, like many other guys had. He thought I was cute, but he left his expectations at the door and just messaged me like I was a normal person. He didn't once mention that I was "hot" or "sexy;" he simply read my profile and talked to me about what was in it and things we had in common. We built up a friendship that way, and then that friendship turned into an opportunity to meet and, eventually, a relationship.

So pay attention to what's on her profile. Talk to her about it. Get a little communication going. Pay attention to her replies; they'll often betray how interested she is. And if you get brave, ask to meet. All she can say is no. And then you move on.

You may get a lot of dead ends, but in the end, girls are just people. Treat them like that and they are more likely to want to pursue something further than online correspondence.
