Move on, you can always pick it up later when you move up there. If you keep trying to get her to meet up with you it might come across as needy.

Before I found this forum I was seeing a French girl who was hot and cold a bit like your situation, we were friends before anything happened. In hindsight I saw that when I was less interested by her the more she wanted me and when I wanted her the less she wanted me, but I didn't realise this at the time.

It messed me up a bit but it taught me a lot, now that I've moved on and not being needy I got an e-mail from her the other day saying she would have married me if I was single now!

I'm not saying don't pay a girl any interest but don't jump though her hoops, do what you want to do and be decisive.
