I believe everyone can find someone. I don't believe there is one destined person. I refuse to believe there is someone written for each of us, including me, because: a) that means I didn't really love anyone before, which is BS, because each time I thought he was the one; and b) what are the chances of meeting The One with billions of people spread over several huge continents?
Generally, I don't believe in any "destiny" stuff. Love including.
