Am I not showing enough interest?

Met a guy at a bar last Friday. He immediately showed interest in me. He texted me that night and for the next 3 days. I responded to him when he reached out, but I would keep my messages short and take a while to respond. On Wednesday he called me, but I didn't answer because I was busy. I didn't hear from him after that. On Saturday I decided to text him and invite him to go hiking with me. He said yes and offered to pick me up. I said no lets just meet there. The hike went well. After it was over, he asked me if I wanted to join him for brunch. I said no because I had work to do. Once I got home from the hike, he texted me and told me he had fun. He also texted me later that evening to let me know what he was up to. I answered him and told him what I was doing. That was yesterday afternoon. I haven't heard from him since.

Maybe I'm completely overthinking this... but I just can't tell if he's interested. I'm asking because I feel a shift in energy on his end. I feel like he's taken a step back from me. As for me, I like him but I tend to not show a lot of interest in a guy that I like right away. I prefer to act in a cool manner.

Any thoughts are greatly appreciated on how I should proceed. Thanks!
