does my crush like me?

Its pretty long but here it goes: I enter school and I go to the 10th grade hallway he looks at me and I see my friend and rush over to her to chat and at the corner of my eye I see him staring then at lunch he keeps turning towards the table I sit at. On his instagram he posts this peice of lyric from his favorite band: And all I can taste is this moment and all I breath is your life. I looked up the lyric and its from a song which is mostly about being afraid to say you love him/her. So, I need to know if he likes me and I always here him say "the girl" and if he does well I'm going to be crying of joy!
