What is his deal?

Anonymous
Okay so I used to be interested in a guy from my job whom I had asked for his IG which was deactivated, but he had reactivated it again so that I could follow him, but he never got around to following me and ended up deactivating his account. I had also asked him for his Snapchat which he gave me and followed me back, but then ended up unfollowing be not too long later. Ever since than I haven’t been greeting him whenever I see him due to the fact that I thought he didn’t mind me so I left it along. Today by my work station he was nearby and called me over and asked me why I don’t say hi to him anymore to which I told him that he doesn’t say hi to me anymore. He had said “So I have to say hi to you first every single time?” to which I responded “my bad”. So I walked away briefly and then I came back to my station and he had told me that I was fake. I didn’t respond Him because I didn’t want to say the wrong thing. He had asked him if I had heard him and I just walked away since I had to go home. On my way to clock out, he passed by me and said that I was mad fake.

I don’t understand after all this time why he would get upset like this and talk to me like that especially since he has a girlfriend (so I have been told). Why would he act like that all of a sudden after a long time and lash out at me like that?
