Depending on ages and type of relationship they have, maybe you shouldn't. You may lose a friend. You have to understand that if he is in fact straight, he is going to feel threatened if you tell him you like him in a sexual way.
tell her!(:
You can tell you're not in love straight forward. You could also explain that it could ruin your friendship.
You go up to him/ her and just tell them straight out "I'm in love with you" and see if they love you back, you'll never know if they do or not unless you try ^^
First become her friend - but not a really good friend, just a friend. Then, just be honest with her. Girls might never tell anyone, but they will be extremely flattered if you straight up tell her how you feel. t
I've had to do it and it;s not easy . be straight up & tell him (: and if your best friend is really your best friend she will understand your feelings for him and trust you.
if your a guy and your friend is a girl how can you tell if she is in love with you?
well first, don't tell her when your in a relationship with her. but after you break up, then go and flirt with her friend, and that will get the message across. unless you rather just tell her straight up, which wouldn't be a good idea, or telling her while your with her.
Just be straight up
if u and him are really good friends it should be really easy 2 tell him. just say it 'im in love with u' dont cut around the bush just say it straight out
Tell her you love her. Tell her you admire her. Tell her the truth. Sincerity works.
Tell them you love them. It's as easy as that. If you're their bets friend, they'll understand.
come straight out and tell her- if shes a real friend she will understand. i agree just tell her
