I met this awesome girl over the weekend. She was mutual friends with some of my friends. We really hit it off and had a great time. I did not ask for her number, but she added me on fb today and posted something funny on my wall. She goes to college in a different town but I really would like to hang out with her more. I am worried about communicating via facebook due to that can turn out looking creepy, but it looks like I have no choice.
What is a good way to go about getting get number/ build attraction with only being friends on fb to go by. (We are both in college by the way, and the other town is about an hour away)
