Why is she so confusing?

so i have gone out with this girl for two times the first time i asked her to go out, and at the end of the first date she asked me to go out, then we texted for some days i initiated contact with her, and she initiated contact with me, then i initiated contact with her and asked her out again and said that is busy, i said ok no problem then i asked again and said again that is busy maybe next week, so i asked the next week and said that is busy again, now she still hasn't initiated to text me since last time, but if i text her she always responds before she used to respond sooner like 1 or 2 hours but now she takes like 5/6 hours sometimes the next day but writes complete books has response and now i don't know what to do, to me seems like she liked me at the dates but now i don't understand it's like something happened in his life or maybe i did something wrong i just don't understand, i asked her if i have done something wrong and she said no and wants to meet me but maybe she was just lying, maybe she just doesn't has enough courage to tell me to go away i don't know, i am so confused now i have no idea what to do uff,

what do you think happened?
