Can any guy decode this first date behavior?

Anonymous
I went on a first date last week which was amazing but I had some minor details that I was hoping someone could provide insight on:

1. I noticed as I was driving that when I'd turn to look at him he was already looking at me, smiling. This happened a few times and when I'd jokingly ask him what he was looking at or why he was smiling he'd just continue to smile and say nothing.

2. At the end of the date he didn't kiss me, he gave me two hugs. The second one lasted longer as if we didn't want to let go.

3. He told me he hasn't been that happy in the longest time and he hasn't smiled that much in years.

4. He texted me as soon as I got home to let me know that he had an amazing time and can't wait to see me again.

I had a beyond amazing time with him but I was just wondering about the no kiss thing. He has told me in the past that he wanted to kiss me (and tried to once but we had to stop after a second due to the location). I'm just surprised he didn't kiss me.

Any thoughts?
