What is the purpose of your call? Are you trying to set another date?
On a separate note, I want to warn you not to go too crazy with the extravagant dates. (Yes, for a kid, they are pretty extravagant.) I don't know what your financial situation is like, but it is awfully difficult for a kid with a limited income to maintain the pace you are setting. Also, you are setting yourself up for difficulties "topping yourself" during birthdays, holidays, whatever. And of course, you want to be sure the girl you are dating likes you for YOU, rather than the nice places you are taking her.
Maybe you can mix in some low-cost/free activities. My son takes his girlfriend hiking and biking quite a bit, and they do videos with a bunch of friends quite a bit. They only go out on dates like you describe about once every 3-4 weeks at this point because his income is limited and he doesn't have a regular job.
I mean, do what you like and can afford to do without becoming resentful, but don't feel like you need to always do something that is costing you $$$.
