Well played my man. Honestly about the coffee and movies thing....I don't think it was a bad idea to say that you had school and stuff. Mainly because that would show that you weren't all about the "sex" and that you were into culture, education and etc....From what it sounds...she seems to be on the same level or somewhat close. So she will respect that. No harm done
I am glad to see that you had a great time and wish you the best!
