This guy I have a crush on thinks I have a boyfriend!

This guy I have a crush on thinks I have a boyfriend because on the front of my binder I have a bunch of pics of me and this guy jimmy. Jim is my uncle but he doesn't believe me because jim is only a year. Older than me. I have pics of us together, dancing and hugging but he doesn't believe that he is my uncle! How can I convince him and maybe get his opinion on if he likes me or not? Help please and tell me what you guys think! Girls and guys please!
