I've reposted this, but why is he not responding?

I really like this guy. He asked me for my number, and we text everyday. He always initiates the text and we have really long convos. We flirt and askes me if i would hang out with him sometime and i said yes and he told me would probably kiss me. I said i was fine with all this and that i was interested. Well this was about three nights ago, and was last convo we had. I rarley see him at school, but when i do we do talk. He had texted me the morning after that convo, but now hasnt texted me since. Last night i was wondering why and decided to text him first saying hey. He still hasnt responded. I know im over analyzing this wayyyy too much and I know he has a life besides texting,but i just really like him and am worried and its weird cuz he went from always texting me to not texring me at all. Should I just relax andbe patient, or is there maybe a reason?Thanks
