I am not satisfied with my blind date. He doesn't talk much. Text me and ask me what I'm doing. How can I refuse him without hurting him?

Relax, maybe he's a little bored and wants to talk to someone. Just say he's ready to rest. Good night

Otherwise, simply reply a few words and chat like a netizen the next day.

His feelings for him are fine, and you don't have to express them in a hurry.
