Are you already dating the best friend? If not, then go for the girl you do like. If you aren't already involved with her friend, then I see nothing wrong with you dating the other girl. However, keep in mind that the one you do like may not want to go out with you for fear of ruining a friendship.
But there is only one way to find out, and that is to talk to the girl that you like. You may also be pleasantly surprised, as well. As for her friend, that is something she will have to think about and deal with should she decide to go out with you. And if she does go out with you, her friend should do the right thing and graciously bow out, and not let it affect their friendship.
It depends, do you like the other girl who likes you? if so, ask HER out. If not, then just ask out the girl you like.
compeet get her befor he dose
you have a fight with them
You can't because if a girl likes you as friend it will never work out..
its not weird its just a love triangle more like a love square, that's sort of weird
You don't....you leave her alone immediately.
Tell him she sees him like a brother , or just as a friend , or she likes someone else.
stop liking the guy or girl that yall both like
I would just switch girlfriends with my friend, but that's just me.
id stop having any contact with her if possible
Ask the girl that she likes you or your friend
Ask if you like him for him, or like him because your best friend likes him - then either ask him out, or do not.
