the saga continues...

okay i've already submitted three questions bout this guy... but something very weird has happened. he doesn't really like me but i like him... alot...
we have this optional class together and it used to have two other guys and a girl in it too. but they all quit. now it's just me and him and the teacher. even though i'm the one that likes him and he doesn't like me back (and he knows i like him) he doesn't seem to mind this at all... what does this mean? HELP!
