Does he like me?

Okay so there's this boy . last year I liked him & even though I've never been sure he liked me back , his Bestfriend Told me he did , does that mean he talked bout me to him?? But anyways , This year recently We see eachother , we don't talk in the halls , it's kind of awkward for us , But he started dating this girl but I would see him look at me & have little glances at me even when he was with her ... does he still like me ? I was with another guy too and when i was taking a picture he saw us & tried to get in the picture ?? I'm so confused please help !
