How do you tell your male close friend that you love him?

Telling him you love him in terms of friendship is easy you can say something to the effect of "You're my best friend I love you like a brother," but if you mean you're in love with him then it gets difficult. You could just be completely straight forward and tell him "I like you as more than a friend" or you could drop hints that you are into him. Before doing this you may want to find out if he is gay or at the very least bisexual, since he may not take the news of you having a crush on him very well. You could lose a good friend by revealing your crush.
