[25/m] wants to tell (23/f) he likes her. Only problem: She lives 1,500 miles away.

We first met at an alumni/student mixer (she was still a student then) earlier this year in NYC (where I live/where she wanted to move to) and we hit it off there. After she graduated, she took a job in Texas, so it's a safe assumption she won't be moving to NYC anytime soon. I was really taken by how funny and smart she was, and we've kept in touch over FB/Twitter for the past nine months. I would definitely like to see if she's open to being in an LDR (or a relationship, period), so what would be the best way to go about finding that out?
