Did something go wrong

So I went on a coffee date (first date) today with this guy and everything seemed to go alright. We enjoyed each other's company. Atleast according to me. I had to leave early and come to work. He told me to text him when i get there. I did like after an hour of getting to work. Then he was like "ok. Ttyl ". So I am still waiting for "later". Lol. I feel like he didn't want to talk more. But the fact that he said he wanted to see me next weekend gets me confused. What do you guys think?
