Did I do something wrong? needing advice

I’ll try and keep this short. I talked to someone who I had met on an online dating app for a few hours and it seemed great. We moved it to a phone conversation and it was even better. She let me know a few times that I was marking everything off on her list of what she wanted in someone and she definitely was marking off everything on mine I told her. We ended up all together talking from 8 in the evening until 4 in the morning so 8 straight hours. I haven’t ever talked to anyone that long from online before and definitely haven’t in ages met someone and talked that long. I really had a good feeling about this. The next day we talked significantly less as she was very tired from staying up the night before and then getting up for work. I completely understood that. The weird thing is my very last few texts. It was still early in the night and she never answered. Ok no big deal. I sent one last final text saying that I knew she probably fell asleep and to sleep good also have a good night. Fast forward to earlier today in the later morning. I wake up to check phone and see that I never got a text back yet. So ok whatever no big deal. I let her know that I hope she’s having a good day. It’s been about five and a half hours or so since that text and still no reply. I definitely know she’s off work by now. I completely get the people get busy. It’s just odd that I didn’t even get a hello or anything. I’m starting to question if I said something wrong or thought this was better than she thought it was. I guess I just need a really vent my frustration because they seemed like it could be something good and I guess it’s not.
