when you’ve gotten to the stage of seriously planning a first date. like both have agreed to one and have a tentative day and time, then you can plan the rest of it over text

Agree with #1. That’s a reasonable time and purpose. Personally I would rather not give my number until we have met in person and I’ve decided I am up for a second date. But if he asks before then and is otherwise decent, I don’t find it a dealbreaker, I just put it off politely for the time being
