What does it mean when a guy walks towards you when he's talking to you?

So I needed to talk to a professor about a paper I turned in. I walked into his classroom and my crush (and im trying to decide if he crushes me back) was the only one in there. I asked my crush if the professor would be back. My crush went into this long story (and started rambling and rambling) about where the professor went. (He's done that before-ramble when he talks to me.) When my crush was talking to me though, he started walking kinda towards me. He isn't hard of hearing, and I'm not soft spoken, so why was he doing this? He didn't have to leave either, because when I entered the room he looked super chill, and when I left he didn't leave the classroom. So that rules out him having to leave, too. I guess my question is, why would a guy walk towards a girl while talking to her. What does this mean? Thanks!

Well he was sitting down before I entered the room. Then he got up when I started talking to him. Plus he was walking straight towards me, not around the room.

I'm not trying to be stubborn, but the way he was walking was straight towards me. It felt personal.
