How to keep girls interested in the period after setting up the first date and the first date? I always try to plan a date within 4 days after getting the number but it's not always possible because of mismatching schedules.

Anyhow, now I'm in a situation where I had two wait two weeks (one week left now) till the first date and I was wondering how I could keep someone interested during long periods like this. In situations like this, I try to text someone once / twice in bursts whenever I have time. (for example: she mentions some things in 3 messages and I reply to these messages and ask her something / give her a something to respond to).

The thing is this often starts to become a tactic to keep in contact; it's the same thing everyday and starts to become boring (not really boring but the excitement of "new" will disappear). I would like some advices how to keep these longer periods of waiting still fun and exciting. Thanks in advance.
