Infuriating, Stupid BOYS!

I have recently thrown myself back into the deep end of the "dating pool". I set up an eHarmony account last October and have slowly eased into the process. Until only recently I had not come across anyone I was even remotely interested in dating. About two weeks ago, however, I reviewed a rather promising profile. He was intelligent, funny, educated, interesting, kind of nerdy (which I like) and he accepted my invitation to "Fast Track" (i.e. skipping the exchanging of pre-fab multiple choice questions and "must have can't stand" lists). We wrote back and forth for a while and I asked him how he would like to proceed with this exchange. He promptly replied with his phone number. So I called him. We spoke on the phone for over 2 hours, which, in my experience, is quite rare for most guys. Towards the end of the conversation he very nervously asked me if I'd like to meet in person for coffee or a drink. I accepted and we made plans for a couple of days later.

We met at the arranged time (except I was late) and proceeded to have (what I perceived anyways) as a very pleasurable afternoon. The conversation flowed easily, I found him ever more interesting, there was a bit of a spark of some chemistry happening... all very good things. I enjoyed his company so much that I invited him to join me and my friends at a happy hour later that week; an invitation that he accepted. Hence my shock when the next day the following showed up in my inbox:

Leslie, Thanks for your email. I was having a hard time last night b/c, though I think you're a smart, attractive, great person, I don't feel that we are a good fit. I'm sorry for telling you this over email, but it's just easier. I wish you the best in your search. Sincerely, Jake

The gall of him! I was infuriated! Not that he isn't interested, but that he led me on and lied to me. I understand that rejection is a part of the dating world, it just isn't going to work any other way. I get that. But why accept an invitation only to back out of it the next day? The following is the email I felt like sending (but, on the counsel of my mom and good friends, didn't!)

Wow, I'm really surprised to read this considering you had accepted a second date. If you didn’t want to go you should’ve just declined because now I feel incredibly mislead. In the future, I’d recommend honesty upfront, lest you contribute to your gender’s stereotypical bad reputation. Thank you at least for doing me the favor of showing me what a ball-less creep you are this early on before I’d wasted any more of my time on you. And yes, it was really lame of you to tell me this over email, you spineless twit. I’d say good luck to you too, but I’m not really feeling that generous towards you anymore. I hope you choke on the coffee I gave you.

I talked with my friend's boyfriend about this "bad male behavior", and while he was able to empathize with the dirtbag and could somewhat explain his possible motives, I'm still lost. Why do most people have such a hard time being honest with each other (and themselves?) Is it really that hard to just say no instead of feigning interest and making promises that you have no intention of keeping? I am so frustrated right now...
