Maybe you guys can help...

So I took a couple classes over the summer and met this guy in one of them. I'm going to call him R. Anyway, I was totally bored and R sat next to me... before I knew it we would be flirting through out the entire class (class was 4.5 hours long 2 days a week for 5 weeks)... anyway. Right after class he went to India for 3 weeks.
I was the first person he called when he got back. We had lunch and ended up spending the whole day together talking. Then we hung out a few nights after that. We went to a movie and then spent a few hours talking. While I was with him I realized I didn't want to date him.
Then he kissed me.
And I knew for a fact I didn't want to date him- it was like kissing my brother (excuse the cliche- and not that I've ever kissed my brother, but you get what I mean, right?)... not romantic or arousing at all...

So the problem is, he acts like we are a couple... like we skipped the whole dating phase of the relationship and headed straight into the talking every night and expecting to hang out during all free hours. He wanted me to get up early the other day to have breakfast with him because he was going to be busy that night... I DON'T get up early for anyone.
He called tonight and left me a long ass voice mail about not having talked to me in a couple of days (its Tuesday, I talked to him sunday...) and he wants me to stop by his work tomorrow so he can see me...
AHHHHH
I don't know what to say to him that isn't going to hurt his feelings. I would totally like him to still be my friend... even if he wasn't going to be in 2 of my classes this semester. Hes a very sweet guy, but I just don't like him like that...
Does anyone have an idea as to what I can say to him? And when? I definately can't talk to him about it while hes at work... but I don't want to drag this out any longer either...
