Guys: if you think a girl is hot do u tell her?

I am in LOVE with wyatt. we have known eachother for a while, and my cousin says he always says that i am hot. one day during dance, wyatt came up to me, and started talking to me. then wyatts lil brother, and 5 of his friends, said that wyatt liked me and wants to go out with me, but he has a girlfriend. wyatt walked away, and smiled, and i didnt know what to say so i didnt say anything. do u still think i have a chance with him, do u think he likes me?
