I recently got dumped by a guy I cared about deeply. In fact I thought he was the One. He said the primary reason was that he is moving soon and he didn't think we had what it took to go the distance so to speak. It hurts because I miss him, but also because now I'm questioning why he felt I wasn't good enough to try to make it work, and how it was so easy for him to walk away. I'm even questioning if I will ever find anyone. I know this is a silly, neurotic way to think and I'm usually not like this. How can I shake this negativity?
