Does this guy like me? Both girls and boys opinions. Best answer is awarded.?

There's this guy I know and have know since high school. We go to the same college and he's a year older. I've never had a boyfriend and he's never had a girlfriend to my knowledge. So when I talk to him it's kind of really awkward. He usually says how are you doing but then keeps walking past me before I answer. Today I went to church and there was a potluck after. I was sitting at a 6 person table and the chair across from me was still empty and he sat down and started talking to me but sometimes the conversation would end and this awkward silence would follow and then he would ask me something else and the same thing would happen. Before he came and sat by me i knew he saw me and was coming over. Even when one of our questions would be answered and there was silence he would still look at me and not look away. Also when the conversation went silent and I continued not to say anything he would just ya. And I don't know it kind of made me nervous. I tried to make eye contact back and i kind of felt like if we were alone he would ask me something or kiss me or something. The conversation did end completely and he said that he's gonna go walk around the room a bit but sometimes when I looked at him he would be looking at me. I just have no experience in this so can you please help?
