Why would a woman say THIS at the end of a first date and then not respond to my messages

So I met a woman on here two weeks ago that I REALLY connected with. We spoke three times on the phone before meeting, and each phone conversation lasted two-three hours. We had so much in common, and we never ran of of things to talk about.

We finally met at a restaurant at a very high-class shopping center. The date lasted a more than reasonable 90 minutes. When it was done, she volunteered to show me around the shopping center (it was my first time there). When we parted ways, she smiled and said "I had a FANTASTIC time" (with heavy emphasis on the word "fantastic).

I thought us seeing each other again was a slam dunk — my instincts about this have been correct before...I waited two days and left a message on her voicemail. She never responded. I wait two more days and texted her, and, again, she did not respond. That was a week ago, and I will make no more efforts to reach out to her. I guess that ship has sailed.

My question is this — why would this woman say these things to me, all but saying her interest in me is mutual and she definitely wants to see me again — and then just flat out not communicate any more?

(If she didn't want to see me again, or even if she felt lukewarm to the idea, I don't think she would have said she had a FANTASTIC time)

She's been back on the web site many times since our date, so I don't think there's another guy in the picture, at least not one in particular.

Just looking for some insight here.

Thanks!
