Am I the only person who thinks that after a date, if a girl has text a guy saying thank you for a lovely evening, the guy should respond with some kind of answer indicating if he wants to see her again or not. Surely it's just basic manners?
Just for manners, yes, he should respond. Maybe not propose another date, that should have been "discussed" during or at the end of the first date, not via text. I would not give a negative response via text.
