There is only one answer for that
Tell her the truth and if she doesn't believe you well then she is not your best friend after all.
Tell him, "If I had feelings for him, I'd be his girlfriend.
There isn't much you can do to convince your best guy friend that he is as amazing as you see him. Sometimes it is best that people remain humble and not see themselves as amazing.
Well, be friends still but just battle it out friendly for the guy and/or convince her to like another guy. It happens to me too, your not alone! The best thing to do when you and your friend likes the same guy is get over it their are other guys out there and you and your friend should not let a boy come in between you and her/his friendship.
Try to convince yourself he's not worth it. Find someone new.
Well i wouldn't give up to easily. this hap pend to me this guy liked my best friend but she knew i liked him but she didn't like him and was determined to convince me she wasn't. Best friends are loyal but if he has made his mind up go with it not everything goes your own way. But i wouldn't let my best friend have him though.
Well what you do is just convince them not to or if that doesn't work just make him convince that he doesn't want anything more than sex in front of her that's all the advice i can give you now byee :)
Have a common interest with him.
You can call him your bgf as in best guy friend
The same thing is happening to me.....my best friend is falling for me,,,,and i know its awkward.....but just pretend nothings happened....fingers cross.....if not you might get distant
Show him Irag combat footage. try YouTube. Show him Irag combat footage. try YouTube.
You cant make a guy like you just because you like them.
go out with some one else
