What should i do in this situation?
I have one very close and best friend. We've known each other long enough. We have common interests. We always help each other whenever possible. Sometimes it seems to me that I have done much more for him than he has for me. I really appreciate him. Before that, he told me that he also considers me his best friend. But today, during our conversation, he said that I might not be up to the best friend. How should I behave in this situation?
