We had an amazing date, insane sex, everything seemed to go great but then she flaked. Why?

So literally everything went really well. She said that she has never came that many times in one night and really enjoyed spending time with me. She lived with her crazy ex and was trying to move out with coincided to our date so i think thats why she left me on read. But anyways, What do you guys think is a good way to reengage?
