Guy's Behavior

Did he like that I was jealous?

I have a coworker who there’s been some weird vibes. I think he may be interested but I feel like he’s definitely at the very least attracted to me. He’s said I smelled nice once or when I do him a favor he’ll say “thank you Alexa” and look at me for longer and it’s weird so I’ll look away.
He’s gotten nervous / flustered while talking to me once.
Well one day he had to train one of his staff and she’s a cute girl around his age and he kept bringing her where I sat to tour her around. I sit in the lobby and he kept bringing her near there.
At the end of their walk I saw them and was rushing to leave but I went to the bathroom first. I think they may have been wrapping up too. When I came out my stall the girl came in and we talked for a few minutes.
I then left the bathroom and my guy coworker was standing a few feet outside and on his phone. ( I guess waiting for the girl ) When I came out I saw him and made a weird face because he scared me and I was walking fast and he got off his phone and was like “what was that?” And was slightly smirking and followed me back out to the lobby and told me bye and to have a good rest of my day.
It seemed like he enjoyed that I was rushing when I saw him or maybe he thought I was jealous of them together or something?
I know they’re strictly just friends though because she was friends with a girl he dated.
