I send my crush a picture and did not reply. What should I do?

So i met an amazing guy at the club. We connected so well l and he was so respectful to me. At first I thought he wanted to hook up with me but, he took me to go out and eat and dropped me off to my car. It was amazing. The next day we were just talking and he told me to send him some pics. I took like 4 picture with little weird faces on them. He started laughing but told me to send him a pic with just a normal smile face. So I did. Before I send him the pic, he did told me that he was going to be at the gym and that he will be waiting for the picture. He said that around 6pm. I was still working but send him the pic at 6 50pm. Pretty much he didn't reply all night and didn't say good night. Around 11pm I just send a message saying " I hope I didn't scare you" and still no reply. I am just waiting to see if he will text me this morning since we have a hang out later on the day. What should I do? I don't want to break the e rules. Am I just freaking out?
