I feel for you. I can understand where everyone else that has provided their advice is coming from. There are billions of people in this world.
However, maybe you are right. Maybe she was the one. I've been mourning over my ex for the past year now. He was my best friend. We did everything together, we had everything imaginable in common, there was nothing I was afraid to ask him, and when he broke up with me, it was like someone had died. Probably worse--I'm fairly convinced that my heart has fallen off the face of the earth.
To everyone urging this man to go wild on a hunt for another female:
Sure, there are tons of people you can date and hang out with. But remember, every person is completely unique. They think differently, love differently, look different, talk different, and so on. You will never be able to find someone exactly like them. You can also spend countless hours with your friends and family, trying to lose yourself and forget your loss if only for a few hours. You can travel to new places, eat new food, cut your hair, and study new things, in hopes of moving on. And you can do all that, and still think about this someone every day of your life. Why is it such a taboo to still be hung up on your ex? Why must everyone's advice be to "move on" and simply stop thinking about them? You can claim to have been through the same sort of scenario, to have your heartbroken. Maybe you have conquered your loss and moved on to a happier existence, but that does not mean that someone else may be able to. I do believe in a love so strong that it can't be explained, and I do believe that after finding this sort of love with someone, it can be almost impossible to go back your ignorant and happy self.
When he describes her as being perfect for him, he doesn't mean she's perfect (as he has pointed out.) Everyone has their flaws--I think a big part of love is a matter of finding someone whose flaws you can deal with and overlook, and finding someone that can overlook your flaws as well.
Regretfullness:
My only advice to you really, is to keep on living, even if it is only to find out what the universe has in store for you. Take all the time in the world you need to mourn. Because no one else but yourself can really come to terms with how you feel.
Love is much more brutal than hatred my friend.
