speechless

there's a quote: i received nothing what i wanted but i received everything that i needed
then here the situation,
i have want a crush for a long time. then unrealized i crushed with one of my best friend. he told and told and told me everything in his days. i know him well, or maybe very well. i know his crush, i know his feelings, i know everything about him. then, what should i do? no no, i mean what should i do to lose this feelings? because he had a crush, he loves someone else, and he doesn't crush on me. and i ask to myself that is God give me what i need?
