The reason I ask: I dated a guy for two years in high school who I really love. Even though he's moved away for college, and I've dated other people, I still get the feeling that he's a missing part of me. We've talked over the past few years, but we both periodically stop/resume contact because it is too painful to talk under the realization that we can't physically be together.
Sometimes I feel like I'm supposed to be with him, but it could be for a million other reasons (he was my first love, he is close with my family, etc.) With billions of people on the earth, is it crazy to think this way?!
