Is my crush shy?

So my crush and I has been talking for 9 months now. However since some months he only reads my message but do not reply. I even showed him his pictures That I stole and saved from his profile. I saw his at a festival on 2 consecutive days. On day 1 he was looking at me when I was not looking. I went to talk to him, he said how are you then hid behind me.. I went away. On day 2 when he saw me he stared at me.. is he shy?
