Does this guy like me? I REALLY need opinions?

So theres this guy I like in highschool, & he looks at me a lot (started happening last year)... so anyways we have a cl together & I sit a couple rows behind him, & i noticed that he turns around to glance at me & will stare at me a lot in cl aswell.. ive also noticed that his friends have looked at me, (one time they were all standing together and were looking at me) & especially one of his friends kinda stares at me... almost as if there's something up....oh, & one time I was walking behind him in the hallway & he glanced over his shoulder to look at me. ive also noticed that sometimes his face (cheeks) will turn a little pink aswell, & he'll touch his hair during cl a lot.... another thing i noticed is that one day when i walked into cl after he saw me he started studdering (he was talking to someone beside him) & he seems flustered when im near him, but the confusing part is that sometimes he'll act like this, but at other times he'll be confident/silly (like his normal self) & basically ignore my existence..... idk but yeah....... what do you think? haha
