Should I be worried he s not responding to my texts?

This guy and I have been talking for a while and he said he wanted me to be his gf. I know its a little far fetched, but we made plans with each other already. Nothing was wrong, everything was normal and the last text was me telling him I m in la. He responded like any other day, but since then, it s been a day and a half that he hasn t responded nor did he read them. We had no problems. I just took it as he is busy and will respond later in a few days. What should I do if he doesn t? Is he uninterested though he seems eager to see me? I don t want to sound despearate, so i only said good morning today and he didnt read that either, so i left him alone hoping he will respond monday.
