No feelings? Or fear of being rejected?

Me and a guy had been heavily talking/texting for a few weeks. Had a lot in common (gym, kids, and even career stuff). Had a great first date and then had a second one the next day. At the end of the second date, we ended up making out and getting a little handsy. When it was over, I was a little embarrassed and I guess I seemed like I regretted it to him, but really I didn’t want him to see me as only hookup material bc I liked him and saw potential.
after that date, he just completely detached. and finally, we spoke yesterday and he said that basically that my reaction kind of killed the emotional side.
I explained my side and asked if he would want to try again? He hesitated for a long time and then hesitantly said ‘no’. I said ‘okay, I wanted to but if you don’t, then I don’t either.’ I said ‘are you sure’ and he hesitated even longer and then said ‘yes’ even more hesitantly. I said, ‘okay, cool and then gave him details about something I was giving him for his daughter. And then just said bye. Not angry or upset. Haven’t talked to him since. A little confused by what happened. What did I do wrong?
