Did he lose interest, and if so how can I move on?

Guy went from smiling at me and staring every time he saw me to literally not making eye contact or trying to be near me. Every time I look he doesn’t really try to engage though now. He just glances but that’s it.
The other day I looked at him and smiled as he was initially heading in another direction and he stopped and saw me and then walked past me. I tried smiling at him but then looked away so not sure if he saw but sometimes I feel like he wants to say something but doesn’t.
I don’t think he’s be pissed necessarily at me since we never really have had a real convo before.
why would a guy avoid a girl like this? I’m not creepy or anything.
