Based on what you shared so far in these 2 threads, I'm more inclined to think you misunderstood her "hints" more than she led you on. Not sure how you asked her about her coldness towards you, but if her reply is as direct as you said it, then it sounded like she was annoyed by you. Perhaps you can reflect on what went wrong and how you can do better next time.

Note: be careful not to blame yourself too much because a failed relationship is very often fault and incompatibility on both sides. Lastly, you can blame or paint her the bad guy all you want, but the whole point of self reflection is to grow yourself and not make this a waste of your time/feelings.
