By what i have told you, does this guy like me??im really confused please read!!!!!?

so there is this guy i really like. we have two cles together, p.e and elective, and we p by each other in the hall sometimes, any who... when he talks to me(which is very seldom) he kinda stutters or doesn't really look at me. and we talk about weird things like once i was playing around in tech, and i went behind the door and then my friend told the teacher to stand in front of the door while i was behind it and it was funny and the whole time "he" was looking at me smiling. and when the teacher finally let me go and i ped by "him" in the hall he said " it would have been pretty funny if he didn't let you go" and i said it wouldn't have been and he said ya and i ran off to catch up with my friends and the other time we were sitting in tech and out of no where he said "shut up brittaney" and i said "you shut up i didn't even say anything!!" and ever sense then he has done the same thing. every now and then i will see him looking at me. i have told all my friends that i liked him, they think im weird cause he is really tall and im kinda short, but i think they kinda make it obvious. oh and did i mention he has a new girlfriend whoes name is brittany as well!! and ever sense they started going out he has changed like talks louder especially around me and isnt the same shy guy he use to be.... any way idk if he likes me. do you think he does
