Search Results: body language that he is interested

So, I work with this guy. I see him every day, so I started saying hi to him when I saw him in the hallways. He's very quiet and, if I had to guess, I'd say he was an introvert due to the fact that I don't really see him talking to people a whole lot. But he always says hi back.

But there are a few times that he has flat out ignored me when we passed.. I was about to say hi and he looked down at his phone really fast, or, one time, I even saw him outside and he was looking over at me and then when I looked at him (took me a second to even realize it was him) he looked away very fast and didn't wave.. that seems weird to me, I feel like the natural thing would be to wave.

But then again, he looks at me a lot.. I sometimes look up and I'll catch him looking at me, and he'll glance away and then back. He never smiles or says hi unless I do it first.. He just gives me a blank look.

We've talked a bit, and his body language has suggested that he's interested - we were talking in the elevator and his legs were pointed towards me and he was standing pretty close, almost like he was "boxing me in" .. but then every time we've talked, he's rushed to get away from me as soon as the elevator ride was over or we exited the building together or something.

I genuinely don't know whether he dislikes me or likes me? or is he just neutral?
