OP, your main problem here is that you're acting needy. You should have waited at least a day after the date to text her rather than texting her the next day. When she is slow to respond to your texts, the worst thing you can do is pursue her more aggressively by calling her and then texting again soon after calling. If she doesn't respond to your first post-date text you have to accept that you will probably never see her again (but if you want you can try a hail-mary restart text a few days to a week later).
You probably also need to work on your in-date game. Did you kino at all on your date? Did you kiss her? From the description you gave it sounds like it could have been a lunch date with a friend. Prioritize physical escalation and logistics so you can isolate her and try for sex. It's usually better to get drinks in the evening for a first date.
