What do you guys think?

So I like this guy and he's always saying how we're just friends because I said I'd never date or talk to anyone in our school (I was kidding but he took it seriously). Even though we're "just friends", I feel like he flirts with me. Here's an example of what I mean 
But then a girl that likes him asked if we talked and he FaceTimes me and asks "do we talk in any other way besides being friendly" and I said no idk why. Then this is after that call. 
So what do you guys think about this?
