Why did he bring up the subject in the first place?

Ok, so here's this guy I like but I'm ok if he doesn't like me back, anyway, I was chatting with him on skype and he told me he liked someone else when I asked if he liked this girl, then I know he won't tell me his crush but he asked me to guess. why? I mean, if he won't tell me, why does he ask me to guess? now he's ignoring me online. What's wrong? Please help.
