It's possible for a close friend to develop romantic feelings, but it's not guaranteed. Signs of potential romantic interest may include increased emotional intimacy, more frequent communication, and subtle flirtation. However, the only way to know for sure is through open and honest communication. If you suspect that your friend may have romantic feelings for you, consider having a heartfelt conversation to clarify your relationship and feelings. It's essential to approach the discussion with empathy and understanding, regardless of the outcome.
