Why do I still like a girl who broke my heart?
Strange question. How would your heart be broken if you didn’t like her? If you didn’t like her, your heart would not be broken.
You just want to be with her and she doesn’t want to be with you. That’s all there is to it. You just need to accept that it’s not going to happen, and it’s painful. That’s your broken heart. It doesn’t have anything to do with her, it only seems like it does. When you accept it, your heart will heal.
