Does he like me??

I think that is a little hard tell from what you have said . It's a 50/50 chance I say . If he does he might be shy . So, you could either wait it out some more and see how he acts or tell him how you feel . I think regardless you should still be able to be friends afterwards .

I think there is potential here but it need to be developed....it's hard to tell especially because he is older than you so you probably don't have a lot of classes with him and don't see him as often as the girls in his grade do.....so I think you should spend more time with him....hugs are nice but if he gives hugs to lots of other people than the hug doesn't mean what you want it to mean...and the eyes incident......for a girl that feels really powerful but it doesn't necessarily indicate that he's into you....try looking in his eyes more often, like every time you talk with him look him straight in the eyes...she if he can handle that...that will show that you can throw his own game back at him.........anyways, spend more time with him if you can, get to know him better and then you'll be able to tell more concretely if he's into you...... hope that helps a little bit
guys are naturally confusing because they think a little differently and act a little differently of course.....keep it friendly though, you may have to settle with being just friends
most importantly be you
