So I got to know this girl, got real close with her, got her number yadayadayada... She agreed to go out on a date with me via text, time and place has been set, it's next Saturday. I just don't know how, what and if I should keep in touch with her via text, to make sure the tension doesn't go away. This doesn't only apply to this particular girl, it's a recurring problem I need to deal with.

Thanks in advance :)

Edit: I get that I need to get the date as early as possible. But in some cases, due to work or parents, or just general unavailability, it's just impossible.
