I've known this guy for almost 4 years, we've dated for 6 months and we have been best friends ever since the break up. Right after he broke up with me he wanted me back I said I would think about it. I waited too long he ended up moving miles away. Two years later I finally made the decision to give him a second chance. Then he tells me to move on. But I really like him and I feel so empty and depressed. What should I do? I really miss him.
