Did I push him away?

I met a guy recently through a hiking group. The day after we did the group hike together, he contacted me to ask if I wanted to hike with him alone the next weekend. We had a great day together, and he asked me to join him on another hike the following weekend. He also found me on Facebook and liked all my recent posts, along with tagging me in his photos of the day. It started to seem pretty clear that he was interested. On our last hike, he even asked if I’d like to accompany him on a Thanksgiving road trip to go kayaking. This was a bit too much too soon, so I politely declined. We shared a beer after our hike, which made for 8+ hours of talking and laughing together. We get along really, really well. I’m quite sure he isn’t seeing anyone else.

But since then (now a little more than a week ago), he has been pretty quiet. A couple texts here and there, no effort to make additional plans. I know he’s been busy with work, but still. Did I seem uninterested when I turned him down for the road trip, or because he’s been the one suggesting everything up to this point? Should I ask him to hang out again, or wait for him to pursue it (or not)? I’m wondering because I have a tendency to be overly distant and give people the wrong impression about my interest.
