I lost my best friend

I met my friend when we were in junior school. At first, I didn’t like him, because he had a big mouth. With the time gone, we became the best friends. I am lucky to find my best friend. We are the best friends until last month. He told me that he loves me but I didn’t accept him. He and I also said that we are still best friends. However, we are not as closed as before. he hoped that I don’t call him again. We have been best friend for so many years. To my disappointed, we lost each other. It is so mirthless.
