Why are all the perfect girls taken?

i just met the most beautiful girl in the world and she was perfect in every way. She was smart, beautiful on the inside and the outside, funny, the list goes on. Your definition of perfect she was it. Problem is she already has a boyfriend. I mean i would do anything for this girl. She was one of the only girls who i have ever met who has been genuinely nice to me all the time. I mean she laughed at all of my jokes, even ones that weren't even that funny, she was so smart, and she cared about the things that was wrong with me, like all my medical problems. i mean what did I ever do wrong, why does "GOD" never want me to be happy. I feel like this girl is my only way to happiness and she is already taken. I'd wait forever and a day to be with this girl, but i feel like that is too long. I don't even want to wait until tomorrow. What the hell should I do to get over it, i feel like i can never be happy. And yes she is perfect in every way, and we both have the exact same things in common in any way you can think, i mean music, games, jokes, movies, personality, sense of humor. I dont even know what more there could be. And she is so exquisite if that is the word to use. Shes a girly girl, a tom boy, and a philosopher all wrapped in one. So what the hell do i do?
