WDoes my best friend likes me?I like him but I don't know how should i tell him?

Well if you don't want your actions to mess up y'alls friendship you really need to think long and hard about what to do because if you do tell him and he likes you too of course y'all start dating but what if then things don't work out so you need to think about that are you willing to lose him as a friend if stuff don't work out but again are you that much into him that even if y'all do go out and things don't work out it was worth it so if your that much into him tell him the worst that would happen was for him to tell you he sees you as a sister. or have one of your other friends casually bring it up when your not around and go from there.
