I soo know what you're talking about. I've had that happen to me before. =( Just tell your friend that you like the same guy as her. When this happened to me, my friend and I agreed that the both of us won't ask him out or anything until one of us stops liking him.
Date him.
First you have to answer the question who do you like more your best friend or the guy you like. If you break them up you have to lose one of them preferably your best friend. To break them up you have to tell your best friend all bad and suspicious things that her boyfriend does. But don't make it obvious that you want them broken up, just be as causal as you can and sneak it into the conversation.
That they have the same taste in clothing.
If your guy friend likes you tell him how you feel about it. If you like him let him know. If you don't, break it to him easily but not to easy that way he understands and you still have a friendship.
wait till they break up then share feelings with him
Be honest with your friend and make sure that your friendship will last, regardless of who ends up dating the guy.
just go a head and let your friend know thta you love the guy that she does
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.
Behave like an adult and be his friend, but let him know that's all you are...not just someone kept in reserve. Then find another guy.
Well if he likes you, you should go for him. But since your friend like him too, you should ask your Friend.
To break up with a guy who is your best friend do this. Talk to him about the matter. Tell him the reason and stop talking to him.
find someone else to like
