Shy guys, is he interested or not interested?

We met at a Halloween party, apparently someone told him I was into him before we started flirting a little when I was buzz. When I sobered up and wave goodbye to be friendly, he grabbed my hand. So I playfully ask for a hug. He hugged me and asked if that’s all I want but he got cocked blocked lmao. I was informed he’s reserve and shy, he don’t really talk about his dating exp much in his friends group. I added him on Instagram, he took like almost a week to follow me. I playfully send a pic sayin happy Halloween, he say happy Halloween back laughing. I said he supposed to send one with a pic back jokingly. But he left me on read 😟 so i kinda forgot him since he hasn’t said nothing. Last night I post a hot pic on story I was gonna go to a rave. He directly msged me right away askin if im going to this rave event. I was shocked cuz it has been 1 month lol. I was like I am and I’ll see him? He said yeah. I playfully said come find me. He laugh sayin there’s too many people. I felt like he wasn’t gonna try, so I didn’t say anything. He did say hi to me when we saw each other. We were with the same people, but he didn’t try to talk or dance with me. I didn’t either cuz I felt shy and his body language seemed off to me. I heard he popped pill as to why he seemed so reserved at the rave event. So I msged him back on Instagram after the event to playfully say he left without sayin bye. He said he know and apologize it was too cold. I playfully say he owes me a hug & greeting next time. He only laugh sayin okay but nothing else…

I don't know is he really shy where he needs me to lead despite knowing I was interested? Or he’s just not interested? It confuses me why he would messsged me if I was going when he didn’t try to talk or dance with me at the event nor said much on Instagram message…
