should I be having this anxiety or not!

I've been seeing this guy at least twice a week now for about passed two weeks. He's nice and sweet but I still don't put anything passed anyone. I have him head. He loved it etc wouldn't stop talking about it. Talks to me every morning and through out the day everyday. Last night we had sex for the first time it went well. Made me food after etc. then we went to sleep. While sleeping he would grab me to hold me etc. in the morning he woke up to go to work and kissed me on the forehead. I decided to get to leave with him for work too. I went to brush my teeth and he showed me where everything is. Then hugged me and said "bye babe" and to lockup the house etc. we were texting on my way home Then he hasn't replied. Idk if he's ignoring me or what. Idk this is where my anxiety kicks in.
