Do they say they like you or act it? Do they give you "hints" or flirt with you? If so they probably like you but you could always ask them instead.
If you have liked other people before and know what it feels like and you feel the same way about your best friend then you like them.
Just be your self. Does your friend know that you like him?
Why must you know?
Best thing to do is just let my best friend know that you like her|him , lol I don't care
well find a way to not hurt your best friend but get the boy to like you or tell your friend you like him and see if she cares
well you have to ask yourself,do you like your friend?
If she is your best friend than just straight up tell her.
If you really like her and you know your best friend will understand say yes' but if you don't like her or you think your best friend will get angry say no
well ive had this happen to me many times. if this guy is aware that you like him, its not right for him to like your best friend. i know he probably cant help it, but that's not right. if he doesnt know you like him, but your friend does, she should be a good friend and not bother with him.
Something that they like. Since they're your best friend you should know what they want.
tell him the truth
Ask them.
