Guys and girls...help!!?

if your friend knows who he likes and wont tell you, it means her and him have a trusting bond. aka friendship. the flirting is probably just for fun, as all high schoolers do it. lol just let time do its thing. if you are meant to be with him, it will be that way. you also need to trust that your friend will not betray you for this boy. and if you like this boy, you need to trust that he would not go after your best friend... let time take its toll. you will be fine! best of luck!
