“He gave me his number then ignored me”

So there is this guy who I know because he works for my parents. He is 3 years older than me and super cool! We talk occasionally when at my parents’ work and what not. So over the New Year’s I went to a festival which he was also attending, we both knew that each other was going as we had talked about it months prior.

About 2 months before the festival was gonna happen, I went to a work function and he was there also, we were talking about the festival and he ended up giving me his number and said give us a call when you’re up there, if anything goes wrong or you wanna hang, and I was like yep cool awesome!

So once the festival comes around I was debating whether to get in contact with him or not, because I was scared he wouldn’t want to hang and because low key I find him attractive and have a little crush. I got up the courage to message him on the first day to which I got no reply. On the third day I rang him and no answer and later that night I messaged him on Facebook so I would know if he read my message. Again no reply. I was feeling kind of bummed because I was really hoping to catch up with him at the festival.

Two days after the festival I posted something on Instagram to which he viewed it, so I know he has been on his phone. Why do you think he would give me his number and then ignore my efforts to reach out? Also please note 4 days after my Facebook message he hasn’t opened it even though he has been online.
