text: There aren't many options for you.\n\nYou have the option of flirting with him to the point that he starts to like you (which is increadibly hard to do) Or you could tell your best friend to 'boycott' him. In other words, the two of you could work together to get him to like only you and not her. She would have to refuse him and if he came along telling her he was in love with her, she'd have to convince him that you were a better pick for him. One way might be to have her completely blow him off. [Which doing a joint effort to get him to like you isn't as hard as it sounds as long as your friend is willing to give him up. (that's what best friends would do)] The thing is though, that in order for it to work, you have to be his #2 choice.
