Did I blow it?!

So last week my accomplice and I sent out a bunch of e-mail to fill my monthly match.com quota. I wasn't expecting a large response, and I wasn't really disappointed. But one guy who I thought was super cute and whose profile actually made me laugh out loud, responded!! Yay! However, I didn't actually read it and respond until three days later. This was not some game playing on my part. I was not near a computer for two days and then was so sick, I didn't even get out of bed. I know, some will say that sick or not I could have turned on my computer! Really, I don't think I could, it took too much energy just to pick up my own head! So when I felt better I saw the e-mail and responded. He has not written back. Oh, I am a little bit sad. Its not like I had met him or even spoken on the phone. But I was just so excited that someone I had written to had written back and maybe was interested in me a little bit. I know I am probably overreacting, I mean, he could still write back, right?
