Lost interest

So there’s this girl I matched with forever ago. She lives like 2 hours away and honestly for whatever reason we just were both super busy and found it hard to ever make plans (both of us were saying just wasn’t the right time this week etc). Well recently we FaceTimed for the first time and she told me during and then after that she wanted to make the drive and see me. Showed super high interest. That day came and she ended up saying she wasn’t comfortable driving so late and asked to reschedule to the weekend. I answered I can try but I’m not sure cause it’s the weekend before Halloween I might be going out. Anyways no answer till today I texted her “don’t tell me she got shy on me.” She texted back something along the lines of saying she’s no longer interested and to have a good night. What exactly do you guys think happened? Just that it had been so long and we never hung? Or somethin else? Just surprised me cause she was very very down and was blowing me up a lot after we had called so seemed interesting. Wondering what your opinion was for the sudden drop off
