This guy knows I like him - he seemed to like me too but claimed he didn't like anyone when I finally admitted it (we were moving to opposite coasts at the time). He replied to my messages at first but now ignores them, I think. For instance he did see my latest message (in which I basically thanked him for having encouraged me to move out here/supported me) - but now it says unread. Why does he ignore me? Why not just unfriend me?
