Does this mean he's not interested?

At the end of my class today, one of my crush's friends went up to this girl saying that he said hi (my crush said hi to her through his friend). The girl said, "I dont care that he's saying hi..." something along those lines. But does that mean that he likes her? He's shown many signs of liking me, and all of them are pretty solid, me and all my friends said it was obvious that he likes me and I really think so too (once he even got jealous of this guy that I was joking around with) though he's nervous to approach me. But this threw me off, does this mean he likes this other girl since he's telling his friend to tell her he said hi?

Now me and this girl don't like each other, she's always glaring at me and competing for attention in class or something
Does this mean he's not interested?
