Well, there are, as others have pointed out, plenty of others out there.
Once you've sampled a few of them, that girl you've been in love with all your life won't seem so damn special.
Even if you're really picky (say, you only like one in 100 girls) and most girls don't like you (say, only one in 100) that still means one in every 10,000 is right for you. With roughly 3 billion on the planet, your odds no longer look so bad.
So go out and start meeting new girls! if you screw up, work out why and pick yourself up to start over.
If you lack the confidence or opportunity to do this right now, there's always porno, lifting weights and writing shitty poetry.
