I recently got mad at him because he started blowing me off big time. I told him that I was mad not because he is busy now, but because he blows off the few plans that we do make at the very last minute. I'd told him like three times how that makes me feel when one night he said "Let me come over tonight so that you can see that I can make an effort" only for him never to show up. So I wrote him a very strongly worded email telling him how mad I was and I also told him how much I really really like him and had started developing feelings for him. The next morning I realized I should have talked to him in person and not sent that e-mail, so a few days later I left him a voice mail just apologizing for the way I said it. he replied saying "don't worry! I don't want you to worry. But it is true, I prefer it when people tell me things like this face to face and not through email. We'll meet to talk about it soon. Please know that I respect you and that I really want to continue being friends :)"
After that we met twice, talked about it, and although we decided to just remain friends everything seemed to go completely back to normal. no awkwardness or anything. The last time I saw him, he called because he wanted to go out. we went clubbing and although he was waaay more distant than other times we've gone clubbing together we still danced together and had a good time (or so I thought).
After that night he has not returned any of my calls or texts. It has been a week. What happened?!
