Why do I feel like a guy who had been dumped twice?

I have a friend, a female friend. She was a good friend of mine but we were studying in two different fields we got separated, but once in a while we talk. But then she happened to tell me that she was thinking if visiting my country and then we started talking daily even before her departure and told me let's meet up and she would give me a call once she arrived. But she didn't call and then I tried talk to her once, but no reply. Then after two years I talked to her she replied after two days. We slowly started talking and again back to normal base then after a day or two she said she was drunk and but I didn't know exactly. In the middle of the conversation she stopped talking and then after that I try multiple times to contact her but no reply again. Can you tell me why this could happen?

Moreover I wanna know why she stopped talking to me.
