Well usually he will tell you. Well that's what happened to me. If he doesn't then you should ask him or get your friends to ask him. If he says no then get closer to him. Do stuff that he likes and get closer to his friends. If he still doesn't like you after that then i would just move on.
You tell him that your best friend likes him too,and tell yo best friend to ignore him he'll eventually love you
You have to tell them
you need to tell your best friend that you do not like them that way.
ask him straight up if he likes you
Tell him she sees him like a brother , or just as a friend , or she likes someone else.
If you like your best friend, and she likes you, too, and you know this for certain, then it would make sense for you to tell her and discuss the situation.
that's messed up...
Tell him i don't think this is right, tell the truth.
Ask her best friend.
No. Just tell your best friend that he is taken. It is her decision from there.
If your boyfriend likes your best friend he is always around her, and only is around you when your with her/him. If he asks "Is Alice there?" And you say no and he doesn't come.. Or if you say yes and he does.. Then, you know he likes her.
Just tell her or him with confidence depending on your gender, sexual preferences, etc.Example of a best-friend turning into a relationship scenario:A guy likes his best friend who's a girl (the guy has to tell her with confidence)A girl likes his best friend who's a guy (the girl has to tell him with confidence)This is an example for straights to go, but the same idea can go for gays
