About me: I am a university freshman, asexual in orientation, Female, and 18 years old.

I'm taking a first year German course with a group of about fifty students, we are all basically strangers. After the first week a guy starts sitting next to me in the almost empty first row of the theatre and breaks the ice by commenting on a desktop background I have, its of an online cartoon series that he tunes into as well.  Since I felt pretty much alone at the new university( I am the only one of my friends who has gone out of state for university besides one of my guy friends who a city over),  I felt like I was beginning to make my first friend. We'd do all the group in-class assignments together and see each other in the hallways a bit and chat. I've been getting the feeling he might have liked me but I really wasn't sure ( I've never dated before.) We dont really know anything about each other beyond names and basic classes/profs we have in common.

About a month and a half after the course has started he suddenly stops talking to me and sits on the opposite side of the lecture theatre. I've tried to approach him a couple of times after class but he just packs up his things and literally runs out of there.  Do you think I may have scared him off somehow?
