Date doesn't reply to texts. Is she even interested?

Hey Reddit,

Recently I've been dating someone, and the dates have been great! We've been on three dates together so far and during them we kiss and touch quite a bit. The issue I've been having is that outside of dates whenever we text she only replies once every 24 hours. So far our only conversations have been about scheduling the next date. Since we only meet once a week, this time I asked randomly if she wanted to hang out the same day on Friday. With today being Sunday I still haven't gotten a reply back at all. A simple "no" would have been a good answer. During the waiting period I also make sure to never double text and am just waiting for a reply. Is she even interested?
