1 or 2 more episodes of google guy finale

Last night i was this close of breaking it off with google guy.THis close. I could feel the words bubbling out of my mouth, but then, i did not. Somehow i just felt really bad. He noticed that i was trying to say something,and i could have sworn he knew what was coming, but somehow, i could not do it. All that came out of my mouth was "so, what are we?" and then, i was trying to break it off with the whole "maybe we are not on the same page" conversation. What the f was i thinking? It was a feeble attempt on my part, i'd acknowledge that. I also proceeded to tell him that i just want to have fun, i dont want a relationship (in the hopes that he wants a relationship, and so, we can shake hands and be friends). And then he said, "you're pretty reserved for just having fun." I wasn't sure what he meant, but this morning, i think what he meant was, "you just want to have fun, but you are not easy." I dont know. And also i felt obliged to make out with him. Isn't this bad? well, he took me to dinner, and i genuinely had a good time with him. I enjoyed his company, but thats about the extent of it. I am not drawn to him, not attracted to him, and absolutely cannot imagine having sex with him. *sigh* i really do have to break it off.
I was thinking of calling him today to give the speech, but i realized that one of my favorite earrings fell while i was in his car. So, i have to get that first before i dump him. And another thing, i found out that he's not sexual through the conversation.
So, what is the best line to dump him:
- I'm sorry, i dont think this is going to work out. I dont feel the same way.
-I'm into someone else.
-Lets just be friends.
-You're a great guy,but i just dont feel chemistry with you. I enjoy your company, but i just dont see you in a sexy way.
-I'm not attracted to you. I dont feel like i want to ever jump in the sack with you.
-You're too uptight. I need someone who's more fun.

Arghhh...is there even a good way to do this? I thought about not answering his calls, or any attempts he made to contact me in the near future. But then, i thought to myself i owe this to him. The least i can do is to be honest. If i were in his shoes, i'd rather someone tell it to my face than take the coward way out.

So, any suggestions?
