This could cause tension in your relationship and who knows she may like the fact. The question is do you just have a crush on him or are you two dating without your friend knowing..... Not knowing specifics if you are dating without her know you just have to be up front and honest and tell her politely - if you just have a crush on him then just tell her I have a crush on your brother and she will likely think its funny or gross considering its her brother.
tell your best friend but tell her not to tell her bro.
just be honest with your feelings or tell your friend first and hear what she has to say
you could say,his name then i like you very much and you are like my brother!!
There is no easy way. Just tell your best friend
Tell your brother first then the best friend....
You should tell her about it, as a best friend she should accept your interests in him. In return she may help you win him over.
Try to tell your friend that you like her brother. This should be done gently in a way that might limit surprise. Tell the brother that you like him. Honesty is best, both in talking to your friend and her brother.
To break up with your best friend's brother do this. Talk to the brother about this. Tell him that you are not interested in it anymore.
Tell them you love them. It's as easy as that. If you're their bets friend, they'll understand.
you kiss the boy and tell him you love him
tell your best friend if they don't mind go for him
He might, it depends on how he is using the term love. It is a very slippery term that has lots of variations and shades. He may love you as a friend, a brother or in a sexual sense. You have to decide what he means or ask him to define it to you.
