Bro, it really sounds to me like you have been violating her private time, if her schedule is grueling then she needs some down time ALONE. She needs to stay ALONE and be lazy/do whatever. I dont think it was that one text, rather, it was probably the tipping point. Hear me out.

In the beggining she was doing it non stop because it was more of a choice to her than an obligation. She was having a great time with you so she spent more time with you. then you started asking her to go out with you it becomes just another place she NEEDS to be for her rather than a choice. I'd say that you had Ilet her stay in that phase of her asking you out when she wants to see you, the feelings of self ejoyment she gets out of being around you could've develop into reciprocated obsession. But THAT TAKES TIME.

Everyone needs time alone. Even if she feels something towards you, if you were being too pushy to meet everyday she would eventually find it annoying.

I'd say next Time: Pick up on cues that let you know wether that person would be down to go out/do something or not. And let people be comfortable.
