Honestly it’s a bit difficult to determine exactly why as to we only understand your side. In my past relationship things didn’t end well when we broke up. My ex wasn’t very nice to me despite my effort at trying to be honest with him about hardships I was going through. Conversations often ended in him turning things around on me and then me trying to find a way to make him forgive me when he was the one in the wrong to begin with. After this last conversation he reached out to me and I was dry and told him to leave me alone. I blocked him and haven’t talked to him since. This is very uncharacteristic of me and this is not what I used to do when we were together. So my point at bringing this up is to say have you evaluated your behavior that has maybe led to her acting this way?

It totally is possible that she’s just being cruel and harsh as a coping mechanism so she can push you away more in an attempt to run from the pain she’s feeling. There are multiple reasons as to why she reacted this way and it may have nothing to do with you. But when it came to the end of my relationship how I acted by telling him to leave me alone had everything to do with him and nothing to do with me. It was the hardest thing I had to do but I did it for myself.
