Why would a guy get silent when he sees me talking to another guy?

So let’s say he is across the room talking to someone else and he sees a guy approach me across the room, he stops talking and stares at me.

He's most likely jealous. I know that I would stop and stare when my old crush would talk to another girl.

He might have a crush on you.
