Replying to OK so I'm kinda new at this?

Yeah, so I've went to all male catholic schools all my life, cept for college, which i got kicked out of, then i joined the Navy, and the male-female ratio there is a billion to one so I've never really been in a relationship. I didn't really care either way up until a month ago, I just decided it would mean more money and more free time to ski and skateboard. So anyways, lets get to the point... one of my friends introduced me to this one girl sometime last week and we I had a lot of fun with her. I got her phone number and such and I met up with her again yesterday, but she kinda bailed at about 8 because she said she had to wake up early today. I was kinda mad after that happened because I go out to sea on Wednesday (only for 24 days though) and these are my last days before I leave. I talked to her today to ask her if she wanted to hang out tomorrow so I could see her one more time. She said she wasnt sure because it'd be only for 2 hours and I gotta drive kinda far to her place. So she said she didn't want to make me drive that far for only 2 hours, I said I didn't care. I guess what I'm trying to say is that she didn't seem too into it. So my question is, is this girl interested in me or should I stop even trying?
