<human>: Can you succinctly summarize the text in 1-3 sentences?

So first, a little background.  I (25/M) just moved to a new town and I have no friends so I tried meeting people on Plenty of Fish.  I've been on many dates through that website, but no one ever sparked my interest.  I met a new girl (24/F) on the website, exchanged a few emails, then a few texts, then agreed to meet for dinner and drinks.  We met on Friday night at one of my favorite restaurants and we had dinner, talked about a lot of stuff, discovered that we had a lot in common, even found out we had like 20 friends in common because she went to college in my hometown.

Everything went great at dinner so we walked over to a nearby bar to have a few drinks and the conversation continued.  We laughed, we talked about serious stuff, she opened up a little about some personal things, we laughed some more.  After it was getting late, I drove her back to her car and before she got out, she asked me if I was going to call her again and I said I definitely would.  I texted her the next day to let her know I wanted to see her again to which she replied that she had a good time, but did not reciprocate the sentiment of hanging out again.  I called her earlier today, but she didn't pick up or call back.

I don't understand, this was the best date I've ever had from POF and we had so much in common, how come the cold shoulder all of a sudden?  What could I have done wrong?  What should I do next?  I would really like that second date so Reddit, what's my next move?
<bot>: Had a great date with girl I met online, thought she was into me, now ignores me.  What to do?
