<human>: Can you condense the text into a few key points?

Hello /r/dating_advice! I'm rather nervous about posting about this, as it seems trivial, but the community here seems rather accepting and kind so I'll go through with it.

I'm a male, age 18, and recently moved into University.  After my first week, a few of my sophomore friends and myself went to a different campus of the same University (4 campuses, 1 University type of thing) to get some actual food and unwind.  I knew I'd be meeting a few of my other friends for a few minutes to catch up and say hi, and I knew they'd be bringing along one of their single friends.  This interested me, and I was excited to meet her.

As my friends and I got to the restaurant and ordered our food, my other friends texted to tell me they were outside.  I walked out and was greeted with huge hugs from my friends whom I had not seen in a while, and a handshake from a beautiful young woman(I'll call her Jane), their single friend.  

We had a chat outside the restaurant for a while but eventually, to my displeasure, I had to return to my other group of friends.  The time i spent talking to Jane was fantastic! She was funny, loved the music I loved and was active and upbeat.  My only wish is that I could have talked to her longer.

After I got back to my dorm that night I added her on Facebook and contempled what I should do next.  Should I message her and try to start a conversation, or should I ask if she wants to hang out later, or do I just let fate take it's course and wait to meet her again when I vist my friends?  There's my dilema.  I'm unsure if it'd be creepy to message her saying how much fun I had talking to her and that I hope to see her again.  I'm usually pretty good and knowing what to do here, but right now I'm dumb founded.  Any advice would be much appreciated!
<bot>: New freshman in University, met a pretty girl, don't know if I should message her and tell her I had fun talking to her, asking if she wants to hang out, etc.  Any Advice is welcome!
