RELATIONSHIP ADVICE PLEASE

So I met this guy on vacation and he seemed to like me after texting me when I gave him my number. His parents are very strict when it comes to the phone but I know their okay with him having a GF. I wanted to see what he thought of me and to tell me if he didn’t like me and it’s been 3 days and he hasn’t responded or read it. Am I being paranoid or is he just not gonna respond ever? I’m 14 and he is 15.
