The guy i like kissed me for more than 4hours....means?

I met this Guy since Feb. but we live an hour away from each other so we communicate thru E-mail. We finally met around May with my roommate and when I saw him in person butterflies in my stomach. I couldn't stop smiling and looking thru his eyes. We are both at the perfect age to get involve in a serious relationship. Anyway second week we met again just me and him.im always nervous around him..he is very smart and our height differences..I'm 5'1 and m he is 6'6". We get looks obviously but height isn't an issue between us. He went on vacation for 3weeks and said he couldn't wait to see me. I don't understand he is not into texting or even calling. But he came back a week earlier from vacation and we saw each other after that and he brought a gift for me. sweet..he said he thinks about me a lot and interested. The next day we meet again then we kiss for 4and a half hours. That's all..we had a greatbkiss but damn that's the longest kiss ever.it could lead to sex but he didn't attempt neither do I. We just had a hot steamy kiss...What is this mean??
