Maybe he likes her but is shy and doesn't want to mess things up before it gets started!
I would say that he wants nothing to do with her.
Perhaps he is shy and unsure?
he could be after you making the first move
well i will need to ask you a question. Is the girl not nice or pretty ? If not than he likes her and if she is than he hates her or doesn't like her at all.
Maybe he's gay.
