Do you think a girl is showing interest after going on two dates with the same guy?

I've been on two dates with this girl and to be honest we had a good time, she enjoyed my company and have discussed alot of things from relationships to other casual stuffs. The surprising thing about the second date is that she went to Canberra a couple of days earlier and she came back on the day of our second date to Hobart.And we went out on that same day!!! she is willing to go out and spend time but we never communicated much with each other ( no phone calls,emails nor facebook chatting) . I called her once just to say hi and I received a good response.She told me that she'll call me anytime to just to say hi or if she wants to hang out- I didn't buy her statement and I'm not looking forward for that.But I have feelings for this girl and I kindly need some advice on whether she is interested or not? Before I make a move.
