Can you please comment on the situation?

I met someone about two weeks ago. The day after we met, I called and we talked on the phone for an hour. The following 7 days, it was all texting. Not a lot but a decent amount. I finally met with her on the 8th day and it seemed it went very well. We talked a bit through text again. But then the communication began tho thin out and for the week thereafter, the conversation became spotty. Sometimes we didn't even say one word. I didn't want to seem annoying, so I let a day or two go by waiting to see if she was interested and would call/write to me. Earlier tonight, after hardly any discussion for the past few days, I asked if she wanted to go out again and she said, "yea def." and continued with telling me to contact her when I get back from my business trip next Thursday. Do you think there is still a chance or is she just being nice at the moment? I'm not sure what to think since I seem to barely talk to her anymore. I really enjoyed the time we spent together and she is so pretty. I'd hate to have lost this one. Thoughts?
