Twice now I've seen him and he noticed me first when he didn't have to?

First time i was in my car and going somewhere early February , 2nd time on Friday at the station he was in between people but cos he's grown a beard (i didn't realize it was him till i saw pics later.) both times he turns to look at me even though he can clearly see its me from the view, first time was a gaze 2nd time was a blink but unlikely to be longer given the circumstances.. A big difference to how he was when he cut me off before, wouldn't even look at me and acted like i wasn't there

I wanna send a message like didn't even realize it was u till after its been ages next time say hello😂 whys it so hard for him to say hello? Its not like we didn't get on and my last message had nothing romantic in it. Haven't even seen anyone else from then except him like
