I miss him, but he don't miss me.

i miss him, but he don't miss me.
-- how u know he don't miss you?
-- maybe he hide his feeling then you don't know?
-- might be he don't know who you are missing?
-- might be he miss you, din lets you know.
-- or else, he is busying his assignment like you. So, he don't want to tell you.
...etc.

Thank Buddies.
I hope I GET WELL SOON.
i miss him.
