Girl not responding to texts..

Anonymous
So, I met this girl on a dating site in September, and we hit it off really well. We've been talking through text and Skype for some months now, and we went on our first date about a week ago, it was enjoyable but there was no romatic contact or anything like that. After that she texted me and said she had a "very nice time" and seemed to agree to a second date next week (this happened 3 days ago) she hasn't replied to any of my messages since then for some reason. Normally, this wouldn't bother me but its just the fact that she ALWAYS responds to texts very quickly, never deterring from this quick response pattern for MONTHS. I know she's reading my text because there is a function on my phone that tells me when messages are read, she's just ignoring them for whatever reason. I don't feel like I said anything weird in the two texts she hasn't responded to, but they did have two direct questions that she didn't respond to (nothing serious, just asking about a movie actor in one text and asking how her day went in the other text). Do you have any insight into what is happening? I can also see that she's still making frequent Facebook posts, so I'm pretty sure she's not simply too busy to respond. I wonder what's up... I feel like I want to ask her, but don't want to feel like I'm pressing the issue. I can understand if she decided she doesn't like me now for whatever reason, but why not just tell me that information instead of ignoring me like this? ...
