My crush and I have known each other for over a year now. We used to work together at a restaurant, but I stopped working there two weeks ago. He was department lead. He's a nerdy guy, but he has a fairly vibrant social life. He would make flirty remarks on occasion, saying that I'm looking pretty and stuff like that. One time over the summer, he had a video game tournament, asked on Instagram if people wanted to watch. I said yes, and he invited me (and only three other people) to watch it.

After summer ended, and it was the first time seeing each other again, he was really shy. We were silent with each other until I started asking him about his summer. It's weird because he acts like he likes me, but he doesn't make any moves. When I left work, he was joking saying "goodbye (my name) I may never see you again". Yesterday, he posted on Twitter that he made a playlist for his crush (I don't know who this crush is). Is it possible I'm the girl he's talking about? Is it possibly someone else?
