If a guy doesn't kiss you on your first date, does that mean he's not interested?

The date went well... He paid. He said that he really enjoyed himself and hoped that I did too. He drove me home. But he never kissed me. I felt like we had chemistry, but he never made the move. That being said, he's 34 and separated (was married for 9 years), so I guess it makes sense that he'd want to take things slowly. Am I reading too much into it, or is a lack of kiss on the first date a sign of disinterest?
