so i'm currently at uni first year, and there is this guy in my college who is a 3rd year student. anyways, i think he's cute and stuff. i asked about him a week or so ago and one of his friends told me he has a crush on someone else so i kept away for awhile, but i dont know if that got anywhere. but later, i talked to him for about an hour at a college bbq. then there was this thing where a group of us were at a club, i walked up to him and started talking to him, just casually. i then went to sit down and he followed, we actually talked for a few hours straight. i left to go to the bathroom a few times and he didn't leave when i got back. anyways, we were sitting really close to each other and stuff and at the end we ended up leaving together to get back to college. a group came back with us, but they walked ahead and he stayed behind and talked to me. but at the end of the night, he said 'well, i guess this is goodbye' [or something similar, you know that phrase] and i stupidly just said 'see you later' and walked back to my room. the next day we were at the food hall together and there was a group of people there already and we all sat together, but we didn't talk [we were sitting a bit too far away].
but we haven't talked since last night! and im a little disappointed because he was really good to talk to and stuff. did i screw it up by walking away last night or is there still a chance? if so, what do i do?
