I got a number and huge interest from this girl, but I cannot set up next date, since I will be away in other country next weekend, and I am kinda busy during the week. Date during the week is kind of no no(?) and to needy, too fast(?), cause it's harder to escalate to sex, due to work next day and waking early.

How should I play this to keep interest, since no texting for long time kind of doesn't work if I don't set up the date very soon. How to keep steam running? ;)
