Re-emerging

Sam cannot leave me alone, but can't seem to be consistent either. Every time I log into my email he seems to chat with me, but I heard nothing from him for over a month prior. I told him that I had started seeing someone, and he was mad. He started asking lots of questions and I answered him very directly. For some reason, though, he keeps asking me if I will come back to him every time he sees me online. Chuck is fantastic so Sam really has no chance. It is also pretty clear that while Sam may be slightly obsessed with me, nothing about his schedule has changed, so I wouldn't be able to spend any time with him which was the original issue with us. I told him today that we could be friends if he likes, but that he needs to accept my decision to be with Chuck and stop pushing for a romantic connection with us. I feel like I am talking to a small child throwing a tantrum. Considering how cool and calm Sam is a rapper, I really didn't expect this kind of behavior from him. Sometimes it seems that the pleading would be a huge stroke to my ego, but instead it just disgusts me. I hope he stops before I start to despise him.
