Guy's Behavior

Is my crush jealous?

Guy I work with (let’s call him Brad) and me have gotten pretty close over the last few months. I have a jokey convos with another guy every now and then. After he walked away Brad looked between me and the guy, smiled and said “What was that?” I started smiling and blushing and he called me out on it and said I wear my emotions on my sleeve.

Next day the guy and I had another convo and Brad asked me a question afterward. I said I didn’t know, I was kinda busy, and he said, “I could see that” with a smirk.

Yesterday I asked Brad if he could give me a ride home, and he said yes. A few minutes later he came back over to me and asked why I didn’t ask that guy to give me a ride. He was smiling, so I know he’s joking. These are just a few examples, but whenever the guy’s name is brought up or he sees us talking to one another, he makes a comment or face.

We joke/flirt a lot and people always notice how close we get and how much we’re around one another. Quite a few have even asked me if we’re dating.
