You have good reason to be confused, and you want to know why? You allowed a friend to act as your "agent" or "middle man" in communicating with your crush. Good quality relationships and clear communication do not work that way. Opt for a "do-over" by going to your crush and confessing that you are confused. Then be ready to say about what. Alternatively, you can flirt with your crush and tell him that rumor has it he has a crush on you. Wait for him to react to your statement by either confirming or denying it. You can always smile big and respond that you are really happy that he likes you too!
My chief point does not allow someone else to communicate on your behalf. Speak on your own behalf so you can communicate precisely the message you want, ask follow-up questions if you don't understand, see the person's expressions, and get the full context of the conversation.
