Secret crush

You like someone but that person does not know. He is one of your brothers bestfriend. He does not know that every time you are around him you get butterflies in your stomach. Every time he comes to your house you are so excited. He talks to you. He says stuff that makes you feel happy and he likes you to. He said once that he wanted to marry you for a toy. When he says that you are really happy and feel like everything is going right. Another time your brother tells him to basically ask you out. What should you have said if he did. I would have said yes. I would be so happy if that actually happened!!
