<human>: Give me the gist of the text in a nutshell

We had some great time together, I really liked her and she is really cute and kind. We didn't have much fights during our relationship, and I tried my best to help her with everything, I even droped college in US to come home when she was sick (2 years ago). And yesterday, she decided to break up with me because she doesn't feel what she felt for me before. Is this even normal? What should I do? She said there is no way we will get together. And yes, she cheated on me 3 years ago, I found out about that 2 years ago, and gave her another chance, she changed really much. So what can I do?

P.S. sorry for my English, I'm depressed, I didn't sleep at all, and can't even eat or drink.
<bot>: She left me because she didn't feel the same after 3.5 years, what should I do? I really love her.
