Libra man and Leo women

So I met this libra man 2 weeks ago online and we met up. First night we got along really well and we had so much in common and really vibed well together. That was a Friday. We ended up sticking side by side and never left each other side until Monday morning. I really like him and enjoy his company and I believe he does too. I met his mom and we made plans for the long run. I knew we were going into it too fast, but I just went along and see how things went. During that week he would text me everyday and would say he miss me. And said he was so lucky to have met me. Every time we saw each other he would compliment me and I would do the same too. It was really nice and everything was going well. Then last week he suddenly didn't text me. I would text him asking how he is and he would say "hey beauty busy busy..." and things seemed okay. We didn't get into any argument or anything. Then I messaged him again if he's okay and expressing that I notice he's a bit distant and ask if everything is okay. He read the message but no reply. Did I do something wrong? What should I do? I really like him, but I'm so confused. Is there anything I can do to fix this?
