Hi & welcome BrokenMiss
I don't understand.
If he didn't care, why would he be crying ~ or talking to you all the time?
If he just wanted to be friends, why did he become so emotional?
Does he know how you feel?
Is it possible that he feels the same way?
Have you discussed this with him?
Perhaps you should.
It sounds like he could be the sort of person you could talk to without ruining your friendship.
Good luck
