How would you deal with this guy trouble?

K so this is a pretty long story sorry

to make it simple i LUV this guy and we used to be best friends and we used to have all periods together

but then we changed grades and all of our classes got changed now we only have two classes together and i really miss him AND the girls in his class are all over him and it drives me crazy because i can see them flirt with him during PE.

and he doesnt talk to me anymore hes always sad and i aked him what was wrong and he said that he doesnt like sharing his personal stuff with other people and im like what (in my head) we used to share EVERYTHING and now he acts like if im some kind of stranger what should i do.How would you deal with this guy trouble?
You can talk to him... or realize that he's just not that into you.How would you deal with this guy trouble?
I guess you just follow what your heart tells you lol, I know how it sounds...
to be honest he is a guy and although he may have lingering feelings for you he is ready to see what else is out there. here is a song for you

you should just talk him and tell him how you feel
just try to talk to him more still, ask him why you guys havent talked in a while and stuff. just do what you think is best for you
