Many thanks Dear alex5710

I will call him tmr. Meanwhile, I may not give him too much pressure. I am going to call him more often and chat with him more.
Actually, a month ago. he wanted to with im very much. but suddently (as he said, he has considered for few days) he want to step backward and became friends. When he back to normal, I will give him more pressure.

Do you think it is a good way to handle?
