Does he like me?

There’s a guy in one of my college classes who I’ve been attracted to since the beginning of the semester, which was like in September. I just recently started sitting next to him in class. He sits in the same seat every time and he recently noticed I exist. It all started after we took our first test and he came out of the classroom after it was over and asked me a question about it. My best friend and sister were sitting with me at the time, and he was staring straight at me and smiling when he asked the question. Then he smiled at me and said “Later.” Then after that, I started sitting next to him in class and one day he asked me if I had moved around and changed seats. So, obviously he notices I was sitting around him. Since then, we’ve been flirting/joking around with each other. He is the kind of guy who the girls flock around and the teachers like. Tons of beautiful girls try to flirt with him and make him laugh but so far, he doesn’t seem interested or really talks to any of them. But every day he sits next to me (even though that’s his normal seat every time) and he will joke around with me and laugh/smile and keep eye contact. He also leans in his chair sometimes facing towards me and one time he offered me his phone when I wanted to look up my grade I got on a quiz. We have similar interests, based on the fact that he, like me, is a dork at heart. I kind of think he is out of my league though, based on his looks. My best friend, who also is in our class, sits behind us and she told me that yesterday he was checking me out when I wasn’t looking at him and had my attention focused on the teacher. Based on what I’ve said, and those signs, does anyone think he likes me or do you think I’m looking too much into this? I’m too shy to just flat out ask him. 😐
