Search Results: reading her signals

Awhile ago, my crush and I went on an impromptu one-on-one outing, and that was kinda the first outing where I've got to know him on a personal level. Our conversations were effortless and endless. He even hinted that he could stay and talk for a little longer, though I told him I had to leave due to a tight schedule. I left a handwritten note on my crush's desk a week after, telling him that I had a fun time hanging out with him and I explicitly asked if he wanted to hang out with me again soon.

I'm 99% sure I saw him reading the note. I left the area right after I saw him read the message, as I was too embarrassed to see his reaction. He didn't text me afterwards, neither has he tried to contact me on social media since then, though I do see him still reading my updates on snapchat (daily). The thing is that we've never spoken online to each other, both before and after our impromptu date. I'm not sure if he's /nicely/ rejecting my invitation or if he's too shy.

We had one final class together afterwards and he didn't try to converse with me. We just ignored each other, which is what we usually do in the class anyway. And the day after our final class, he saw me walking down the corridor and suddenly decided to acknowledge me with a smile and a wave. I'm really confused by the signals that he's giving. I'm not sure if I should ask him about this further (and risk invading his personal space) or simply to move on.
